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.

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.

Did it on an average power of less than 5mA which made solar power easy to add. No power. No wires. More on this project in the next few weeks.

Projects for books, project for articles and customer specific devices. The thing we were missing was an easy way to build prototypes or one-off devices for experiments or customers that are robust and easy and quick to wire up. That was the thought for Grove connectors. The second criteria is that we had to get the power way down from the Arduino. At least 10 times lower. That would give us solar power flexibility that we have not been able to achieve with the normal Arduino or the Raspberry Pi. We looked at the entire board and did away with anything that was not strictly necessary and worked on the power consumption that was left. \u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p2\"\u003e\u003cspan class=\"s1\"\u003e\u003cem\u003eOne key piece of the design was to make sure we could put the processor to sleep and then wake it up from internal and external sources.

Like all the time. So, using the Mini Pro LP, we build a solar powered WeatherRack reader and then we use a transmitter to send it back to the station inside the lab.

The thing we were missing was an easy way to build prototypes or one-off devices for experiments or customers that are robust and easy and quick to wire up. That was the thought for Grove connectors. The second criteria is that we had to get the power way down from the Arduino. At least 10 times lower. That would give us solar power flexibility that we have not been able to achieve with the normal Arduino or the Raspberry Pi. We looked at the entire board and did away with anything that was not strictly necessary and worked on the power consumption that was left. \u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p2\"\u003e\u003cspan class=\"s1\"\u003e\u003cem\u003eOne key piece of the design was to make sure we could put the processor to sleep and then wake it up from internal and external sources.

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).

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.

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.

We have needed one of these for a long time. In previous projects, we were continually needing relays (mostly latching relays) to switch power on and off to computers and devices, to switch from solar to wind and a variety of other chores. What a pain! Now we have developed and designed a Quad Power Management board incorporating I2C controlled 4 Independent Solid State Relays each with LEDs to show what is going on with the board. Each solid state relay is able to switch 20V and 2.3A. You can switch DC signals and analog signals (with proper conditioning - you need to add a DC Offset for analog signals). This board is magic to us for building power systems. There are 4 Additional GPIOs provided on the board (thanks to the SX1502 as in the above board) that can be used as GPIOs, interrupts or a programmable logic gate as above. Software drivers for Arduino and Raspberry Pi Included! We are using this board extensively in our new SunRover semi-autonomous robot design.

It takes 3 batteries to get up to about ~12V. The problem is that all of our Solar Powered Charging system is designed to charge 3.7V LiPo batteries. Our solution? Use two QPM boards to switch the batteries from a series to parallel connection and then charge the batteries from SunAirPlus. The QPM board even has two inputs per device. One with a protective diode and one without the diode.

Each of these six solar panels can be switched by a Quad Power Management board and be connected in different ways to provide more power to the subsystem (Motors, Arduino or Raspberry Pi) depending on what needs it at the time and the Sun. We are using four QPM boards to accomplish this.

The winters are cold up here in the frozen north and LiPo batteries and electronics need to be kept warm to keep working. We are accomplishing this by using the QPM board to switch 10W\/20 Ohm resistors, one in each compartment. We have temperature sensors in each compartment that will give us the feedback we need to moderate the heat sent to the resistors. How do we control the heat coming off of each resistor? We pulse the QPM switches to only power the resistor for the amount we need. If we want 3.6W, we turn the QPM switch on 1\/2 of the time (7.2W\/2). We can make it generate just enough heat to keep the compartment at the right temperature. Very cool. Or hot in this case. \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_243a3f78fcdb033c42f0b749b1c97f8b_original-2.jpg?16614707158960697788\"\u003e\u003cimg height=\"521\" width=\"680\" alt=\"243a3f78fcdb033c42f0b749b1c97f8b_original-2\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_243a3f78fcdb033c42f0b749b1c97f8b_original-2.jpg?16614707158960697788\" class=\"aligncenter size-full wp-image-2295\"\u003e\u003c\/a\u003e\n\u003cdiv data-id=\"4093248\" class=\"template asset\"\u003e\u003c\/div\u003e\nQPM - Battery Stacker \/ Unstacker Applicaton\u003c\/div\u003e\n\u003ch2\u003e\u003cspan style=\"font-size: 1.5em;\"\u003eQuad Power Management Loaded Test\u003c\/span\u003e\u003c\/h2\u003e\nTo test the current carrying capability of the QPM board, a 10 Ohm 10W resistor and measure the current through the resistor.

We have needed one of these for a long time. In previous projects, we were continually needing relays (mostly latching relays) to switch power on and off to computers and devices, to switch from solar to wind and a variety of other chores. What a pain! Now we have developed and designed a Quad Power Management board incorporating I2C controlled 4 Independent Solid State Relays each with LEDs to show what is going on with the board. Each solid state relay is able to switch 20V and 2.3A. You can switch DC signals and analog signals (with proper conditioning - you need to add a DC Offset for analog signals). This board is magic to us for building power systems. There are 4 Additional GPIOs provided on the board (thanks to the SX1502 as in the above board) that can be used as GPIOs, interrupts or a programmable logic gate as above.

The three applications below are from a new SwitchDoc Labs project, SunRover.

The other two computers are an Arduino Mega 2560 (the power management computer - also does weather sensing) and the brains of SunRover, a Raspberry Pi 2 Quad Core computer. The electronics will be packaged in a BUD enclosure as below. Note the Circuit Board Condo that we designed and 3D printed.

It takes 3 batteries to get up to about ~12V. The problem is that all of our Solar Powered Charging system is designed to charge 3.7V LiPo batteries. Our solution? Use two QPM boards to switch the batteries from a series to parallel connection and then charge the batteries from SunAirPlus. The QPM board even has two inputs per device. One with a protective diode and one without the diode. Perfect for our application. \u003ca href=\"http:\/\/www.switchdoc.com\/wp-content\/uploads\/2015\/04\/IMG_0969.jpg\"\u003e\u003cimg height=\"712\" width=\"930\" alt=\"IMG_0969\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_IMG_0969-1024x784.jpg?13760602946785384368\" class=\"aligncenter size-large wp-image-2288\"\u003e\u003c\/a\u003e\n\u003ch3\u003eSolar Panel Multiplexer\u003c\/h3\u003e\nSunRover has 6 3.5W\/6V solar panels. These will be on a \"wing\" across the top of SunRover. Each of these six solar panels can be switched by a Quad Power Management board and be connected in different ways to provide more power to the subsystem (Motors, Arduino or Raspberry Pi) depending on what needs it at the time and the Sun. We are using four QPM boards to accomplish this. SunRover Motors subsystem - up to 6 solar panels Raspberry Pi subsystem - up to 4 solar panels Arduino Power Management subsystem - up to 2 solar panels \u003ca href=\"http:\/\/www.switchdoc.com\/wp-content\/uploads\/2015\/04\/IMG_0976-2.jpg\"\u003e\u003cimg height=\"712\" width=\"930\" alt=\"IMG_0976 2\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_IMG_0976-2-1024x784.jpg?1693467713238327663\" class=\"aligncenter size-large wp-image-2289\"\u003e\u003c\/a\u003e\n\u003ch3\u003eRobot Compartment Heater\u003c\/h3\u003e\nOur third example application of the QPM board is a resistive compartment warmer. The winters are cold up here in the frozen north and LiPo batteries and electronics need to be kept warm to keep working. We are accomplishing this by using the QPM board to switch 10W\/20 Ohm resistors, one in each compartment. We have temperature sensors in each compartment that will give us the feedback we need to moderate the heat sent to the resistors. How do we control the heat coming off of each resistor? We pulse the QPM switches to only power the resistor for the amount we need. If we want 3.6W, we turn the QPM switch on 1\/2 of the time (7.2W\/2). We can make it generate just enough heat to keep the compartment at the right temperature. Very cool. Or hot in this case. \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_243a3f78fcdb033c42f0b749b1c97f8b_original-2.jpg?16614707158960697788\"\u003e\u003cimg height=\"521\" width=\"680\" alt=\"243a3f78fcdb033c42f0b749b1c97f8b_original-2\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2455\/2113\/t\/8\/assets\/description_image_243a3f78fcdb033c42f0b749b1c97f8b_original-2.jpg?16614707158960697788\" class=\"aligncenter size-full wp-image-2295\"\u003e\u003c\/a\u003e\n\u003cdiv data-id=\"4093248\" class=\"template asset\"\u003e\u003c\/div\u003e\nQPM - Battery Stacker \/ Unstacker Applicaton\u003c\/div\u003e\n\u003ch2\u003e\u003cspan style=\"font-size: 1.5em;\"\u003eQuad Power Management Loaded Test\u003c\/span\u003e\u003c\/h2\u003e\nTo test the current carrying capability of the QPM board, a 10 Ohm 10W resistor and measure the current through the resistor.

Since we are mostly interested in moist environments when we are using this device, this is a problem.

Grove TSL2591 Sunlight / IR I2C Sensor

The TSL2591 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from 188 uLux up to 88,000 Lux.

The TSL2591 contains both infrared and full spectrum diodes. That means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see.  This sensor has a 600,000,000:1 dynamic range. You cannot change the I2C address, so keep that in mind.

The TSL2591 contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes. Integration of both channels occurs simultaneously. Upon completion of the conversion cycle, the conversion result is transferred to the Channel 0 and Channel 1 data registers, respectively. The transfers are double-buffered to ensure that the integrity of the data is maintained. After the transfer, the device automatically begins the next integration cycle.



The current draw is extremely low, so its great for low power data-logging systems. about 0.4mA when actively sensing, and less than 5 uA when in power-down mode.

UV Transparent Fused Quartz Window Available

If you are putting a Grove TSL2591 Sunlight / IR  sensor in a weather proof container, you should use a far-UV transparent Silica Quartz plate for the window over the sensor.  You will also get better readings for the visible and IR TSL2591 readings.

 

However, remember most plastics and glass are basically impervious to UV radiation (that’s why your Photogray sun glasses don’t work well in a car) so you need to use a special plastic or what we prefer, Silica Quartz. These Quartz JGS1 windows will let the UV through.

Spectrum

This content is from Wikipedia - Spectrum.

A spectrum (plural spectra or spectrums[1]) is a condition that is not limited to a specific set of values but can vary infinitely within a continuum. The word was first used scientifically within the field of optics to describe the rainbow of colors in visible light when separated using a prism. As scientific understanding of light advanced, it came to apply to the entire electromagnetic spectrum.

Lumen

 

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total "amount" of visible light emitted by a source. Luminous flux differs from power (radiant flux) in that luminous flux measurements reflect the varying sensitivity of the human eye to different wavelengths of light, while radiant flux measurements indicate the total power of all electromagnetic waves emitted, independent of the eye's ability to perceive it. Lumens are related to lux in that one lux is one lumen per square meter.

For some examples:

  • Dark night: 0.001—0.02
  • Moonlight night: 0.02—0.3
  • Cloudy day indoor: 5—50
  • Cloudy day outdoor: 50—500
  • Sunny day indoor: 100—1000
  • Suitable for reading: 500—600
  • home video camera: 1400
