This is the RGB and Gesture Sensor, a small breakout board with a built in APDS-9960 sensor that offers ambient light and color measuring, proximity detection, and touchless gesture sensing.
With this RGB and Gesture Sensor you will be able to control a computer, microcontroller, robot, and more with a simple swipe of your hand.

The APDS-9960 is a serious little piece of hardware with built in UV and IR blocking filters, four separate diodes sensitive to different directions, and an I2C compatible interface. Each APDS-9960 also has a detection range of 4 to 8 inches (10 to 20 cm).

• Pins Detail: VL (optional power to IR LED), GND (Ground), VCC (power to APDS-9960 sensor), SDA (I2C data), SCL (I2C clock), and INT (interrupt).
• Using Chip: APDS-9960
• Power Supply: 3.3v
• Communication: IIC communication protocol
• Size: 20mm * 15.3mm
