Touchless gestures are the new frontier in the world of human-machine interfaces. By swiping your hand over a sensor, you can control a computer, microcontroller, robot, etc. One manufacturer has even created a touchless toilet that flushes when you move your hand over the tank. The Avago APDS-9960 offers ambient light and color (as clear, red, green, and blue) measuring, proximity detection, and gesture sensing.
The APDS-9960 RGB and Gesture Sensor board breaks out the pins on the Avago APDS-9960 so you can easily use it in a variety of projects. The APDS-9960 uses the I2C interface for communications.
