This is the touch-less gestures sensor a HMI (Human Machine Interface) by swiping your hand over the sensor, which controls a computer, microcontroller, robots or home, automotive, industrial gesture switching or ambient light and color measuring and proximity detections. The Avago / Broadcom APDS 9930 / 9960 RGB and Gesture Sensor board break out pins so you can easily use it in variety of projects together with your SBC and MCU.
The APDS-9930
APDS 9930 provides a digital ambient light sensing, IR LED and a complete proximity detection system in a single chip. The proximity function offers plug and play detection to 100mm without front glass. The proximity detection feature operates well from bright sunlight to dark area. The wide dynamic range also allows for operation in the ability to put the device into a low power mode between ALS (Ambient Light Sense) and proximity measurement. The APDS 9930 is particularly useful for display management with purpose of extending battery life and providing optimum viewing is diverse lightning conditions.
The APDS-9960
APDS 9960 is an advance Gesture Detection Sensor together with proximity, Ambient Light Sense, and RGBC (Color Sense). The gesture detection utilizes four directional photo-diodes to sense reflected IR energy (Source by the integrated LED) to convert physical motion information example are velocity, direction and distance) to a digital data. The architecture design of the gesture engine features automatic activation based on proximity engine that results an ambient light subtraction, cross-talk cancellation, dual-8bit data converters, power saving inter-conversion delay, 32 data-set FIFO, and interrupt driven i2C bus communication. The gesture engine accommodates a wide range of mobile device that has a gesturing equipment to control UP-DOWN-RIGHT-LEFT feature or more complex gesture can be accurately sensed.
