Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor - STEMMA QT / Qwiic
This breakout is chock full o' sensors! Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB and Gesture Sensor. When connected to your microcontroller (running our library code) it can detect simple gestures (left to right, right to left, up to down, down to up are currently supported), return the amount of red, blue, green, and clear light, or return how close an object is to the front of the sensor. This device uses an I2C interface so it's easy to wire up and use.
The APDS9960 from Avago Technologies has an integrated IR LED and driver, along with four directional photodiodes that sense reflected IR energy from the LED. Its proximity detection feature allows it to measure the distance an object is from the front of the sensor (up to a few centimeters) with 8-bit resolution.
Since there are four IR sensors, you can measure the changes in light reflectance at each of the cardinal locations over time and turn those changes into gestures. Our interface library can detect directional gestures (left to right, right to left, up to down, down to up), but in theory more complicated gestures like zig-zag, clockwise or counterclockwise circle, near to far, etc. could also be detected with additional code.
The APDS9960 has a configurable interrupt that can fire when a certain proximity threshold is broken, or when a color sensor breaks a certain threshold.
For your convenience, we've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting so it can be easily used with your favorite 3.3V or 5V microcontroller. New! We've updated this board to be STEMMA QT compatible. We've now included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just wire up to your favorite microcontroller or computer with a plug-and-play QT cable to light/color/proximity data ASAP.
- As of March 16, 2020 - We've updated this sensor to our 0.7" x 1.0" STEMMA QT standard for sensors. There are now four mounting holes and two STEMMA QT connectors for plug-and-play connectivity! The schematic and pinout is the same, only the mechanical shape has changed.
