Si1143 Gesture Sensor

This sensor has three infrared sensors positioned at three corners of the sensor, each one measuring variations of light. By placing your hand over the sensor, you varies the light that reaches it and therefore, it can detect your hand movements from top to bottom, bottom to top, left to right and right to left.

This Gesture Sensor was designed to work with microcontroller and can be embedded on an independent electronic circuit.
