Basic breakout board for the TEMT6000 Ambient Light Sensor. TEMT6000 is a silicon NPN epitaxial planar phototransistor in a miniature transparent mold for surface mounting onto a printed circuit board. The device is sensitive to the visible spectrum. Only what you need, nothing you don’t. Sensor acts like a transistor – the greater the incoming light, the higher the analog voltage on the signal pin.

Applications:

1. Ambient light sensor for display backlight dimming in:
2. Mobile phones
3. Notebook computers
4. PDA’s
5. Cameras
6. Dashboards

Package Includes:

1 x SparkFun Ambient Light Sensor Breakout – TEMT6000

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.

LightRanger 10 Click as its foundation uses the VL53L4CX, a ToF (Time-of-Flight) optical distance sensor with an extended target detection range from STMicroelectronics. This ToF sensor integrates a VCSEL (vertical-cavity surface-emitting laser), which emits an entirely invisible 940nm IR light, totally safe for eyes (Class 1 certification), and a SPAD (single-photon avalanche diode) array which helps the VL53L4CX to achieve the best ranging performance even when a Click board™ is hidden behind a wide range of cover glass materials. Specifically designed for long-range and multi-target measurements, the VL53L4CX provides very accurate distance measurements up to 6m with excellent results over short distances and 18° FoV (Field of View), which improves performances under ambient light. Thanks to ST’s patented algorithms, the VL53L4CX can detect multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 80cm and dynamic smudge compensation for targets below 80cm. Like all Time-of-Flight sensors based on ST’s FlightSense technology, the VL53L4CX records an absolute distance measurement regardless of the target color and reflectance.

LightRanger 10 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings with a maximum clock frequency of 1MHz. This Click board™ can be enabled or disabled through the EN pin routed to the CS pin of the mikroBUS™ socket; hence, offering a switch operation to turn ON the initial boot sequence of the VL53L4CX. It also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, indicating when a ranging measurement is available.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Applications: Can be used for presence (object) detection, distance measurement, industrial ranging, inventory control, and more

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.
