The ADS111\/5 are extremely easy to configure and design into a wide variety of applications, and allow precise measurements to be obtained with very little effort. Both experienced and novice users of data converters find designing with the ADS1115 to be intuitive and problem-free. The ADS111\/5 consists of a ΔΣ analog-to-digital (A\/D) core with adjustable gain, an internal voltage reference, a clock oscillator, and an I2C interface. An additional feature available on the ADS1115 is a programmable digital comparator that provides an alert on a dedicated pin. All of these features are intended to reduce required external circuitry and improve performance. The ADS1115 functional block diagram is shown above. The ADS1115 A\/D core measures a differential signal, VIN, that is the difference of AINP and AINN. A MUX is available on the ADS1115. This architecture results in a very strong attenuation in any common-mode signals. The converter core consists of a differential, switched-capacitor ΔΣ modulator followed by a digital filter. Input signals are compared to the internal voltage reference. The digital filter receives a high-speed bitstream from the modulator and outputs a code proportional to the input voltage. The ADS1115 has two available conversion modes: single-shot mode and continuous conversion mode. In single-shot mode, the ADC performs one conversion of the input signal upon request and stores the value to an internal result register. The device then enters a low-power shutdown mode. This mode is intended to provide significant power savings in systems that only require periodic conversions or when there are long idle periods between conversions. In continuous conversion mode, the ADC automatically begins a conversion of the input signal as soon as the previous conversion is completed. The rate of continuous conversion is equal to the programmed data rate.

The ADS111\/5 are extremely easy to configure and design into a wide variety of applications, and allow precise measurements to be obtained with very little effort. Both experienced and novice users of data converters find designing with the ADS1115 to be intuitive and problem-free. The ADS111\/5 consists of a ΔΣ analog-to-digital (A\/D) core with adjustable gain, an internal voltage reference, a clock oscillator, and an I2C interface. An additional feature available on the ADS1115 is a programmable digital comparator that provides an alert on a dedicated pin. All of these features are intended to reduce required external circuitry and improve performance. The ADS1115 functional block diagram is shown above. The ADS1115 A\/D core measures a differential signal, VIN, that is the difference of AINP and AINN. A MUX is available on the ADS1115. This architecture results in a very strong attenuation in any common-mode signals. The converter core consists of a differential, switched-capacitor ΔΣ modulator followed by a digital filter. Input signals are compared to the internal voltage reference. The digital filter receives a high-speed bitstream from the modulator and outputs a code proportional to the input voltage. The ADS1115 has two available conversion modes: single-shot mode and continuous conversion mode. In single-shot mode, the ADC performs one conversion of the input signal upon request and stores the value to an internal result register. The device then enters a low-power shutdown mode. This mode is intended to provide significant power savings in systems that only require periodic conversions or when there are long idle periods between conversions. In continuous conversion mode, the ADC automatically begins a conversion of the input signal as soon as the previous conversion is completed. The rate of continuous conversion is equal to the programmed data rate. Data can be read at any time and always reflect the most recent completed conversion.\u003c\/p\u003e\n\u003ch2\u003ePinOut\u003c\/h2\u003e\n\u003cp\u003e\u003cimg class=\"aligncenter wp-image-5903 size-full\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_Grove4ChADCBoardGrove.png?16608421722137696282\" alt=\"Grove4ChADCBoardGrove\" width=\"517\" height=\"311\"\u003e \u003cimg class=\"aligncenter wp-image-5904 size-full\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_Grove4ChADCBoardJP.png?16150076510053785548\" alt=\"Grove4ChADCBoardJP\" width=\"517\" height=\"311\"\u003e\u003c\/p\u003e"});window.BOLD.common.Shopify.saveVariant(3340540641310, { variant: {"id":3340540641310,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"0058-GRV4CADC-DSBT","requires_shipping":true,"taxable":false,"featured_image":null,"available":true,"name":"Grove - 4 Channel 16 Bit Analog to Digital Converter","public_title":null,"options":["Default Title"],"price":1995,"weight":6,"compare_at_price":2495,"inventory_quantity":157,"inventory_management":"shopify","inventory_policy":"deny","barcode":"","requires_selling_plan":false,"selling_plan_allocations":[]}, inventory_quantity: 157, product_id: 229332680734, product_handle: "grove-4-channel-16-bit-analog-to-digital-converter", price: 1995, variant_title: "Default Title", group_id: '', csp_metafield: {}});window.BOLD.common.Shopify.saveProduct("grove-128x64-i2c-oled-board-for-arduino-and-raspberry-pi", 229322031134, {"id":229322031134,"title":"Grove 128x64 I2C OLED Board for Arduino and Raspberry Pi","handle":"grove-128x64-i2c-oled-board-for-arduino-and-raspberry-pi","description":"\u003cp\u003eThis is a very readable Grove 4 Pin Connector I2C OLED module.

The SCL\/SDA controlling fans out to fourdownstream channels. Any individual channel or combination of channels can be selected via I2C. Four interrupt inputs (INT3–INT0), one for each of the downstream pairs, are provided. One interrupt (INT) output acts as an AND of the four interrupt inputs. When you receive an interrupt, you read the interrupt register on the device to find out what channel interrupted you. An active-low reset (RESET) input allows the TCA9545A to recover from a situation in which one of the downstream I2C buses is stuck in a low state. Pulling RESETlow resets the I2C state machine and causes all the channels to be deselected, as does the internal power-on reset function. The TCA9545A allows the use of different bus voltages on each pair, so that 1.8-V, 2.5-V, or 3.3-V parts can communicate with 5-V parts, without any additional protection.

Four interrupt inputs (INT3–INT0), one for each of the downstream pairs, are provided. One interrupt (INT) output acts as an AND of the four interrupt inputs. When you receive an interrupt, you read the interrupt register on the device to find out what channel interrupted you. An active-low reset (RESET) input allows the TCA9545A to recover from a situation in which one of the downstream I2C buses is stuck in a low state. Pulling RESETlow resets the I2C state machine and causes all the channels to be deselected, as does the internal power-on reset function. The TCA9545A allows the use of different bus voltages on each pair, so that 1.8-V, 2.5-V, or 3.3-V parts can communicate with 5-V parts, without any additional protection.

The library is easy to use and hides the complexity of the interface to the sensors. The C++ class has two Interrupt Service Routines (ISR), one each for the anemometer and the rain bucket. The wind vane is connected to an Analog to Digital Converter (ADC) input pin on the Arduino. Note that the C++ class is designed to be a singleton, in other words, you only can interface one sensor package without some additional work (mostly involving Interrupts). The article in \u003ca href=\"http:\/\/www.raspberry-pi-geek.com\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRaspberry Pi Geek magazine\u003c\/a\u003e discusses this in detail. There are two main modes for the class.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_SAMPLE\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_SAMPLE mode means return immediately after asking for the wind speed. The wind speed is averaged at sampleTime or since you last asked, whichever is longer. If the sample time has not passed since the last call, the class returns the last calculated wind speed. That means that you will never see changes faster than the specified sample time. This allows you to not wait for the wind speed, you can just grab the last valid reading.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_DELAY\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_DELAY mode means to wait for the set sample time to expire and return the average wind speed at the expiration. You would use this if you want to make sure you have the latest value and your program architecture allows you to pause for the sample time before continuing. Which mode you use depends on the specific software architecture of your Arduino application. Typically, I use SDL_MODE_SAMPLE because I can tolerate not having a current value of wind speed.

The library is easy to use and hides the complexity of the interface to the sensors. The C++ class has two Interrupt Service Routines (ISR), one each for the anemometer and the rain bucket. The wind vane is connected to an Analog to Digital Converter (ADC) input pin on the Arduino. Note that the C++ class is designed to be a singleton, in other words, you only can interface one sensor package without some additional work (mostly involving Interrupts). The article in \u003ca href=\"http:\/\/www.raspberry-pi-geek.com\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRaspberry Pi Geek magazine\u003c\/a\u003e discusses this in detail. There are two main modes for the class.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_SAMPLE\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_SAMPLE mode means return immediately after asking for the wind speed. The wind speed is averaged at sampleTime or since you last asked, whichever is longer. If the sample time has not passed since the last call, the class returns the last calculated wind speed. That means that you will never see changes faster than the specified sample time. This allows you to not wait for the wind speed, you can just grab the last valid reading.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_DELAY\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_DELAY mode means to wait for the set sample time to expire and return the average wind speed at the expiration. You would use this if you want to make sure you have the latest value and your program architecture allows you to pause for the sample time before continuing. Which mode you use depends on the specific software architecture of your Arduino application. Typically, I use SDL_MODE_SAMPLE because I can tolerate not having a current value of wind speed.

The Grove Enable Line is pulled down by a 43K resistor so if it is disconnected, the USB PowerControlV2 is compatible with the original USB PowerControl.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e \u003c\/p\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ch2 class=\"column\"\u003e\u003cspan\u003eFeatures\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCan Switch the Power to any plugged into the Female A USB port\u003c\/li\u003e\n\u003cli\u003eOn\/Off Controlled by a single control line Implements Hysteresis on Control line\u003c\/li\u003e\n\u003cli\u003e3.8V\/3.3V Turn On\/Off Voltage with LIPOBATIN\u003c\/li\u003e\n\u003cli\u003eGrove Digital Connector - ENABLE and CONTROL your USB Port\u003c\/li\u003e\n\u003cli\u003eOver Current Protection\u003c\/li\u003e\n\u003cli\u003eThermal Shutdown\u003c\/li\u003e\n\u003cli\u003eReverse Current Blocking\u003c\/li\u003e\n\u003cli\u003eCan be connected to GPIO Pin or directly to LiPo Battery\u003c\/li\u003e\n\u003cli\u003eSupports both Arduino and Raspberry Pi\u003c\/li\u003e\n\u003cli\u003eHas Dual USB ports - no more cutting USB cables\u003c\/li\u003e\n\u003cli\u003eWill work with SunAir and SunAirPlus Solar Power Controllers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"column\"\u003e\u003ca href=\"http:\/\/www.switchdoc.com\/2015\/08\/secrets-of-the-usb-powercontrol-application-notes\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cstrong\u003eApplication Note Published *Secrets of the USB PowerControl!*\u003c\/strong\u003e \u003c\/a\u003e\u003c\/h2\u003e\n\u003cdiv class=\"column\"\u003e\n\u003cul\u003e\n\u003cli\u003eMaking the USB PowerControl on by Default, when connected to a GPIO that needs to be initialized (like the Pi and Arduino GPIOs)\u003c\/li\u003e\n\u003cli\u003eTurning off the USB PowerControl even if the battery is higher than ~3.3V and lower than ~3.8V.\u003c\/li\u003e\n\u003cli\u003eControlling the USB PowerControl with a 3.3V GPIO Line, WITHOUT a buffer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"page\" title=\"Page 5\"\u003e\n\u003cdiv class=\"section\"\u003e\n\u003cdiv class=\"layoutArea\"\u003e\n\u003cdiv class=\"column\"\u003e\n\u003ch2\u003e\u003cspan\u003eGrove GPIO Control Circuitry for the USB PowerControl\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThis circuitry is provided to allow the USB PowerControlV2 to be controlled by either LIPOBATIN or the state of the CONTROL Line (J3 Pin 1).

The Pi uses an Internet service called NTP to set the clock on power up if the Internet is available.

A Raspberry Pi being sent up in a balloon or a Pi working in the remote caribbean, like Project Curacao. The Raspberry Pi keeps pretty good time, but only if it is connected to the Internet. The Pi uses an Internet service called NTP to set the clock on power up if the Internet is available. It then calls the NTP servers (some are actually hosted by the National Institute of Standards and Technology (NIST) and linked to their atomic clocks).

It has 8 Grove Digital Connectors and 3 Grove I2C connectors (which form an I2C Hub). We are always running out of GPIOs on the Raspberry Pi. We wanted a clean way of adding more GPIO ports (Digital Grove ports) and we decided this was the way to do it. 8 Digital Grove ports (and a bonus 2 extra Grove I2C) is the way to do it in style. This board connects to the I2C bus on the Raspberry Pi and adds 8 additional 3.3V GPIOs to the Pi. You can also make them 5V GPIO pins if you wish. Connects to a Grove I2C connector and supplies 4 channels of Grove Analog plugs for your projects.

It allows easy serial expansion of I\/O through a standard I2C interface. GPIO devices can provide additional control and monitoring when the microcontroller or chipset has insufficient I\/O ports, or in systems where serial communication and control from a remote location is advantageous. These devices can also act as a level shifter to connect a microcontroller running at one voltage level to a component running at a different voltage level. The core is operating as low as 1.2V while the I\/O banks can operate between 1.2V and 5.5V independent of the core voltage and each other. Each GPIO is programmable via 8-bit configuration registers. Data registers, direction registers, pull- up\/pull-down registers, interrupt mask registers and interrupt registers allow the system master to allow the system master to program and configure 8 GPIOs using a 2 wire standard 400kHz I C interface. \u003cstrong\u003ePLD (Programmable Logic Device)\u003c\/strong\u003e The SX1502 offers a unique fully programmable logic functions like a PLD to give more flexibility and reduce external logic gates used for standard applications. Pins IO4-IO7 are available for PLD use on the 8GPIO board. Since the whole truth table is fully programmable, the SX1502 can implement combinatory functions ranging from the basic AND\/OR gates to the most complicated ones with up to four 3-to1 PLDs or two 3-to-2 PLDs which can also be externally cascaded if needed. In all cases, any IO not configured for PLD functionality retains its GPIO functionality while I\/Os used by the PLD have their direction automatically set accordingly. Please note that while RegDir corresponding bits are ignored for PLD operation they may still be set to input to access unused PLD inputs as normal GPI (PLD truth table can define some inputs to have no effect on PLD output) and\/or generate interrupt based on any of the PLD inputs or outputs bits.

It has 8 Grove Digital Connectors and 3 Grove I2C connectors (which form an I2C Hub). We are always running out of GPIOs on the Raspberry Pi. We wanted a clean way of adding more GPIO ports (Digital Grove ports) and we decided this was the way to do it. 8 Digital Grove ports (and a bonus 2 extra Grove I2C) is the way to do it in style. This board connects to the I2C bus on the Raspberry Pi and adds 8 additional 3.3V GPIOs to the Pi. You can also make them 5V GPIO pins if you wish. Connects to a Grove I2C connector and supplies 4 channels of Grove Analog plugs for your projects.

It allows easy serial expansion of I\/O through a standard I2C interface. GPIO devices can provide additional control and monitoring when the microcontroller or chipset has insufficient I\/O ports, or in systems where serial communication and control from a remote location is advantageous. These devices can also act as a level shifter to connect a microcontroller running at one voltage level to a component running at a different voltage level. The core is operating as low as 1.2V while the I\/O banks can operate between 1.2V and 5.5V independent of the core voltage and each other. Each GPIO is programmable via 8-bit configuration registers. Data registers, direction registers, pull- up\/pull-down registers, interrupt mask registers and interrupt registers allow the system master to allow the system master to program and configure 8 GPIOs using a 2 wire standard 400kHz I C interface. \u003cstrong\u003ePLD (Programmable Logic Device)\u003c\/strong\u003e The SX1502 offers a unique fully programmable logic functions like a PLD to give more flexibility and reduce external logic gates used for standard applications. Pins IO4-IO7 are available for PLD use on the 8GPIO board. Since the whole truth table is fully programmable, the SX1502 can implement combinatory functions ranging from the basic AND\/OR gates to the most complicated ones with up to four 3-to1 PLDs or two 3-to-2 PLDs which can also be externally cascaded if needed. In all cases, any IO not configured for PLD functionality retains its GPIO functionality while I\/Os used by the PLD have their direction automatically set accordingly. Please note that while RegDir corresponding bits are ignored for PLD operation they may still be set to input to access unused PLD inputs as normal GPI (PLD truth table can define some inputs to have no effect on PLD output) and\/or generate interrupt based on any of the PLD inputs or outputs bits.

WeatherRack\u003c\/a\u003e, ArgentData Weather Sensors, SparkFun Weather Meters SEN-08942 in one C++ class. The library is easy to use and hides the complexity of the interface to the sensors. The C++ class has two Interrupt Service Routines (ISR), one each for the anemometer and the rain bucket. The wind vane is connected to an Analog to Digital Converter (ADC) input pin on the Arduino. Note that the C++ class is designed to be a singleton, in other words, you only can interface one sensor package without some additional work (mostly involving Interrupts). The article in \u003ca href=\"http:\/\/www.raspberry-pi-geek.com\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRaspberry Pi Geek magazine\u003c\/a\u003e discusses this in detail. There are two main modes for the class.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_SAMPLE\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_SAMPLE mode means return immediately after asking for the wind speed. The wind speed is averaged at sampleTime or since you last asked, whichever is longer. If the sample time has not passed since the last call, the class returns the last calculated wind speed. That means that you will never see changes faster than the specified sample time. This allows you to not wait for the wind speed, you can just grab the last valid reading.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_DELAY\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_DELAY mode means to wait for the set sample time to expire and return the average wind speed at the expiration. You would use this if you want to make sure you have the latest value and your program architecture allows you to pause for the sample time before continuing. Which mode you use depends on the specific software architecture of your Arduino application. Typically, I use SDL_MODE_SAMPLE because I can tolerate not having a current value of wind speed.

WeatherRack\u003c\/a\u003e, ArgentData Weather Sensors, SparkFun Weather Meters SEN-08942 in one C++ class. The library is easy to use and hides the complexity of the interface to the sensors. The C++ class has two Interrupt Service Routines (ISR), one each for the anemometer and the rain bucket. The wind vane is connected to an Analog to Digital Converter (ADC) input pin on the Arduino. Note that the C++ class is designed to be a singleton, in other words, you only can interface one sensor package without some additional work (mostly involving Interrupts). The article in \u003ca href=\"http:\/\/www.raspberry-pi-geek.com\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRaspberry Pi Geek magazine\u003c\/a\u003e discusses this in detail. There are two main modes for the class.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_SAMPLE\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_SAMPLE mode means return immediately after asking for the wind speed. The wind speed is averaged at sampleTime or since you last asked, whichever is longer. If the sample time has not passed since the last call, the class returns the last calculated wind speed. That means that you will never see changes faster than the specified sample time. This allows you to not wait for the wind speed, you can just grab the last valid reading.\u003c\/p\u003e\n\u003ch3\u003eSDL_MODE_DELAY\u003c\/h3\u003e\n\u003cp\u003eSDL_MODE_DELAY mode means to wait for the set sample time to expire and return the average wind speed at the expiration. You would use this if you want to make sure you have the latest value and your program architecture allows you to pause for the sample time before continuing. Which mode you use depends on the specific software architecture of your Arduino application. Typically, I use SDL_MODE_SAMPLE because I can tolerate not having a current value of wind speed.

Connect the \"+\" end of the diode to the \"+\" side of the solar panel (or the line from the solar panel to the SunControl Board) and the \"-\" side to the negative (\"-\") side of the panel.

How can we get our Raspberry Pi to see the lightning? We do that with the new WeatherSense Lightning Detector. The solar powered lightning detector sniffs out the lightning up to 30km (18.75 miles) away and reports it back to your Raspberry Pi safe inside the house using 433MHz radio technology. This sophisticated sensor can detect the difference between local sources of EMF (Electro Magnetic Frequency) noise and the real bolts of lightning. Why do we want it outside? Because your house, monitors, phone, computers and the Raspberry Pi itself are sources of electrical noise that makes it harder for this sensitive lightning detector to do its job. And we have designed the system to just sip (Solar!) power and send back necessary reports to your Raspberry Pi for your display and analysis.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eWhat is WeatherSense?\u003c\/h2\u003e\n\u003cp\u003eWeatherSense is an open source wireless protocol for sending information from remote sensors to your Raspberry Pi.

You would think it would be pretty easy, but it turns out it is not. It's not just like a giant spark. Well, it is a giant spark, but there are lots of other things that make electrical noise that can be confused for lightning. Your computer (even your Raspberry PI and Arduino!), your car, the motor in your refrigerator, your cell phone, your computer monitor, your AM\/FM radio and even your TV. They all make electrical noise that can be confused with Lightning.\u003c\/p\u003e\n\u003cp\u003eThe Thunder Board detects Lightning and provides a distance estimate to the “leading edge” of an incoming storm. The phrase “leading edge” is a bit misleading, since it suggests that one is in the direct path of the storm. In fact, for the purposes of the Thunder Board, the leading edge is simply the closest edge of the storm, which may never actually arrive if the storm delivers a glancing blow nearby.\u003c\/p\u003e\n\u003cp\u003eHowever, its distance away from you – regardless of where it is heading – is the most relevant information. A lightning strike creates an electromagnetic pulse that can be detected using an external antenna tuned to 500 kHz, with a bandwidth of 33 kHz. An analog front-end (AFE) demodulates and amplifies the antenna signal, and a watchdog circuit alerts the lightning detector once an event crosses its threshold. However, numerous other electromagnetic events create high-energy events. It is important that such non-lightning “disturbers” not be misinterpreted as lightning – and vice versa.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/files\/6dbada0e9150ad65b5e0ef943086bd1e_original_jpg_480x480.jpg?v=1615844545\"\u003e\u003c\/p\u003e\n\u003cp\u003eWe then decide whether the event has the characteristics of a lightning strike. If not, it is rejected as being the result of a disturber. If it decides that it is lightning, the energy of the event is calculated and stored, and then the storm distance is calculated based on that and prior events. An interrupt then completes the process so that the Arduino or Raspberry Pi can retrieve the information and take action.\u003c\/p\u003e\n\u003cp\u003eSounds like magic? It's not. But it is pretty cool that you can build a kit that does this.\u003c\/p\u003e\n\u003cp\u003eJohn has created a video explaining how the lightning detector works and how to tune

How can we get our Raspberry Pi to see the lightning? We do that with the new WeatherSense Lightning Detector. The solar powered lightning detector sniffs out the lightning up to 30km (18.75 miles) away and reports it back to your Raspberry Pi safe inside the house using 433MHz radio technology. This sophisticated sensor can detect the difference between local sources of EMF (Electro Magnetic Frequency) noise and the real bolts of lightning. Why do we want it outside? Because your house, monitors, phone, computers and the Raspberry Pi itself are sources of electrical noise that makes it harder for this sensitive lightning detector to do its job. And we have designed the system to just sip (Solar!) power and send back necessary reports to your Raspberry Pi for your display and analysis.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eWhat is WeatherSense?\u003c\/h2\u003e\n\u003cp\u003eWeatherSense is an open source wireless protocol for sending information from remote sensors to your Raspberry Pi.

You would think it would be pretty easy, but it turns out it is not. It's not just like a giant spark. Well, it is a giant spark, but there are lots of other things that make electrical noise that can be confused for lightning. Your computer (even your Raspberry PI and Arduino!), your car, the motor in your refrigerator, your cell phone, your computer monitor, your AM\/FM radio and even your TV. They all make electrical noise that can be confused with Lightning.\u003c\/p\u003e\n\u003cp\u003eThe Thunder Board detects Lightning and provides a distance estimate to the “leading edge” of an incoming storm. The phrase “leading edge” is a bit misleading, since it suggests that one is in the direct path of the storm. In fact, for the purposes of the Thunder Board, the leading edge is simply the closest edge of the storm, which may never actually arrive if the storm delivers a glancing blow nearby.\u003c\/p\u003e\n\u003cp\u003eHowever, its distance away from you – regardless of where it is heading – is the most relevant information. A lightning strike creates an electromagnetic pulse that can be detected using an external antenna tuned to 500 kHz, with a bandwidth of 33 kHz. An analog front-end (AFE) demodulates and amplifies the antenna signal, and a watchdog circuit alerts the lightning detector once an event crosses its threshold. However, numerous other electromagnetic events create high-energy events. It is important that such non-lightning “disturbers” not be misinterpreted as lightning – and vice versa.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/files\/6dbada0e9150ad65b5e0ef943086bd1e_original_jpg_480x480.jpg?v=1615844545\"\u003e\u003c\/p\u003e\n\u003cp\u003eWe then decide whether the event has the characteristics of a lightning strike. If not, it is rejected as being the result of a disturber.

The smoke from the fires in California spread over the entire western half of the United States. What is the local air quality at your house? You can find out with the new WeatherSense AQI sensor. What is AQI? AQI stands for Air Quality Index and it is a general measurement of the density and size of particulates in the air you are breathing. This sensor puts out an accurate measurement of the AQI at your house or school, so you can make the right decision of what to do on a given day.

The smoke from the fires in California spread over the entire western half of the United States. What is the local air quality at your house? You can find out with the new WeatherSense AQI sensor. What is AQI? AQI stands for Air Quality Index and it is a general measurement of the density and size of particulates in the air you are breathing. This sensor puts out an accurate measurement of the AQI at your house or school, so you can make the right decision of what to do on a given day.

Since we are mostly interested in moist environments when we are using this device, this is a problem. SwitchDoc Labs has come up with a solution for these inexpensive soil moisture detectors by designing a small board that shuts the power off to the moisture sensor with a command from the controlling computer. This board is the GrovePowerSave. It also is used to shut down power to unneeded Grove devices in Solar Powered systems.\u003c\/p\u003e\n\u003cp\u003eDepending on the amount of moisture and impurities in your water and soil, the HR Grove Moisture Detector will outlast similar moisture sensors by 4 to 5 times.\u003c\/p\u003e\n\u003cp\u003eIf you are building a solar powered plant monitoring system, this has the side benefit of reducing your power requirements for the sensor from 35mA to almost nothing (depending on how often you read the sensor!).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eHow To Use\u003c\/h2\u003e\n\u003cp\u003eYou have three grove Cables that are supplied with the HR Soil Moisture Sensor.

Since we are mostly interested in moist environments when we are using this device, this is a problem. SwitchDoc Labs has come up with a solution for these inexpensive soil moisture detectors by designing a small board that shuts the power off to the moisture sensor with a command from the controlling computer. This board is the GrovePowerSave. It also is used to shut down power to unneeded Grove devices in Solar Powered systems.\u003c\/p\u003e\n\u003cp\u003eDepending on the amount of moisture and impurities in your water and soil, the HR Grove Moisture Detector will outlast similar moisture sensors by 4 to 5 times.\u003c\/p\u003e\n\u003cp\u003eIf you are building a solar powered plant monitoring system, this has the side benefit of reducing your power requirements for the sensor from 35mA to almost nothing (depending on how often you read the sensor!).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eHow To Use\u003c\/h2\u003e\n\u003cp\u003eYou have three grove Cables that are supplied with the HR Soil Moisture Sensor.

Grove 128x64 I2C OLED Board for Arduino and Raspberry Pi

Grove 128x64 I2C OLED Board for Arduino and Raspberry Pi

Regular price: Sold out
Sale price: $8.00
Unit price: per

This is a very readable Grove 4 Pin Connector I2C OLED module. Due to the high contrast of an OLED display, it is readable even at small fonts. This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED. This breakout is used with an I2C interface. The design is completely 3.3V/5V-ready, with an onboard regulator and built in boost converter. Connects to either Arduino or Raspberry Pi controllers with no level shifters required. No Grove Cable included. No external reset pin required. Software drivers are available here.

This is an inexpensive I2C OLED display using Grove Connectors for the Arduino / Raspberry Pi / ESP8266

This product is a very flexible Grove 4 Pin Connector I2C OLED module. This display is a 128x64 OLED, with each pixel being turned on or off by the SSD1306 controller chip included in the module. You can display fonts, graphics and even animations with this crisp, high contrast display.

What are Grove Connectors?

Grove Connectors are standardized easy to connect and use cables for prototyping devices. See the SwitchDoc tutorial on Grove Connectors. This product was designed specifically for the new SwitchDoc Labs kickstarter, OurWeather: https://www.kickstarter.com/projects/sunair/ourweather-weather-kit-for-stem-kids This breakout is designed to be used with a Grove I2C Connector. The design is completely 3.3V/5V-ready, with an onboard regulator and built in boost converter. Connects to ESP8266, Arduino or Raspberry Pi controllers with no level shifters required. No Grove Cable included. No external reset pin is required. We have a power-on reset circuit on board. The board is trivial to connect up to your system. Plug it into a 5V or 3.3V Grove connector on your Raspberry Pi, Arduino or ESP8266 and you are ready to go. The I2C address used is 0x3C (not 0x3D as some other displays). The SSD1306 specification can be downloaded here.
