Скачать или смотреть IR gesture click - Example

IR Gesture click is a mikroBUS™ add-on board that enables contactless gesture recognition, along with ambient light and proximity sensing capabilities with the APDS-9960 IC. This sensor integrates an LED and four directional photodiodes that receive the reflecting light. An internal gesture engine deduces the velocity, direction and distance of nearby objects (while cancelling the ambient light). You can implement a variety of gestures, from from basic directional swipes (up, down, left or right) to more complex combinations. Since the chip can work as a proximity sensor, the gesture engine can be configured to wake up automatically when a user’s hand approaches. The board communicates with the target board MCU through the mikroBUS™ I2C interface, with an additional hardware inerrupt pin (INT). IR Gesture click uses a 3.3V power supply.
