This is the BH1750 16-bit Ambient Light Sensor from Rohm. Because of how important it is to humans and most other living things, sensing the amount of light in an environment is commonplace to get started when learning to work with microcontrollers and sensors. It’s a small, capable and inexpensive light sensor that you can include in your next project to add the detection and measurement of light.

The BH1750 provides 16-bit light measurements in lux, the SI unit for measuring light, making it easy to compare against other values like references and measurements from other sensors. The BH1750 can measure from 0 to 65K+ lux, but with some calibration and advanced adjustment of the measurement time, it can even be convinced to measure as much as 100,000 lux!

Sensors tend to come in small packages and the BH1750 is no different.

Packaged on a PCB in our STEMMA QT form factor, the BH1750 comes integrated with a voltage regulator and level shifting circuitry to allow it to be used with 3.3V devices, like a Feather M4 or Raspberry Pi, or 5V devices, such as an Arduino.

This is a STEMMA I2C breakout for the Infineon OPTIGA TRUST M SLS 32AIA.

OPTIGA Trust M is the next generation of Trust X. OPTIGA Trust M brings RSA 1K/2K + ECC256/384.

A crypto authentication chip much like the ATECC608 STEMMA we put into the shop last week, but with: ECC NIST P256/P384, SHA-256, TRNG, DRNG, RSA® 1024/2048 and 4.5K of user memory.

This chip can store your private keys securely, as well as generate true random numbers, which is what we’ve got going on in this demo below. Check out https://github.com/Infineon/optiga-trust-m for the Arduino library

Comes with a bit of 0.1″ standard header in case you want to use it with a breadboard or perfboard.  Four 2.5mm (0.1″) mounting holes for easy attachment.

Package Includes:

1 x Adafruit Infineon Trust M Breakout Board

The Adafruit AS7341 10-Channel Light / Color Sensor Breakout is a multi-channel spectrometer, which is a special type of light sensor that is able to detect not only the amount of light present but also the amounts of light within different wavelengths. This means that you can use it to detect much better than the human eye is capable of, what color or colors of light is present.

The AS7341 packs within its 3x2mm footprint 16 different sensors that can detect 8 separate, overlapping bands of colored light. As if that weren’t enough, it also includes sensors for white light as well as Near Infra-red light, and even sensors made specifically for detecting light flicker at specific frequencies from things like indoor lighting.

The super-human color measuring capabilities of the AS7341 can be used to quantify the specific makeup of whatever interesting colors you can point it at, and can do so with more accuracy and specificity than a well-trained artist.

This is possible thanks to the impressive collection of sensors in the AS7341 being routed through a 16-bit 6-channel ADC that takes the raw measurements and converts them to digital values that can be read out over I2C.

11 readable individual sensor elements (10 light channels plus flicker detection) don’t exactly fit through a 6-channel ADC all at once, so the chip includes a so-called Super MUX (SMUX) that allows you to route the signal from any sensor to an ADC channel. Now that’s some super multiplexing! The sensor also has GPIO and interrupt pins that can allow it to communicate directly with other sensors, or the microcontroller itself.

All of this capability is made accessible by mounting the sensor on a STEMMA QT form factor breakout board, complete with level shifting circuitry and SparkFun Qwiic compatible Stemma QT connectors. This means that you can, without needing to solder, connect our AS7341 breakout into your 3.3V or 5V microcontroller of choice be it an Arduino Uno, Raspberry Pi, or one of the many CircuitPython-compatible boards.

Applications:

1. High-precision reflective color point and spectral measurements.
2. Fluid color, turbidity, or reagent-based constituent analysis.
3. Spectral power distribution and passive ambient CCT measurement for home and building automation.
4. High-end display color management.

Features: 

1. Precision color, spectral composition, and distribution measurements
2. 8 optical channels distributed over the visible spectral range + clear and NIR channels realized via silicon nano optic interference filter deposition technologies.
3. Low power consumption and efficient I²C communication.
4. Integrated ambient light flicker detection on-chip and light source detection through the NIR channel.
5. Electronic shutter/trigger and synch control.
6. GPIO can be used as an external trigger input or light source synchronization output.
7. External photodiodes to expand detection range.
8. GPIO can be used as input for external photodiodes including a mid-IR range.

1 x Adafruit AS7341 10-Channel Light / Color Sensor Breakout – STEMMA QT/Qwiic

The LTR390 is one of the few low-cost UV sensors available, and it’s a pretty nice one! With both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. You can use it for measuring how much sun you can get before needing to covering up.

Unlike the Si1145, this sensor will not give you UV Index readings. However, the Si1145 does UV Index approximations based on a light level, not true UV sensing. The LTR-390, in contrast, does have a real light sensor in the UV spectrum. It’s also got a much much simpler I2C interface so you can run it on the Arduino or Python microcontrollers/microcomputers with ease. Unlike the GUVA analog sensor, the biasing and ADC is all internal so you don’t need an ADC.

To make using it as easy as possible, we’ve put the LTR390 on a breakout PCB  in our Stemma QT form factor with a sprinkle of support circuitry to give you options when testing. You can either use a breadboard or the SparkFun qwiic compatible STEMMA QT connectors, and compatibility with 5V voltage levels as commonly found on Arduinos, as well as 3.3V logic used by many other boards like the Raspberry Pi or our Feathers.

Package Includes:

1 x Adafruit LTR390 UV Light Sensor – STEMMA QT/Qwiic
