Abstract
A proximity sensor with multi-directional movement detection is provided. The proximity sensor may include an ASIC chip; at least three light sources configured to emit light in a particular sequence; and a photo detector configured to receive light and generate an output signal. The multi-directional proximity sensor may have a first proximity sensor with at least one side surface and a second proximity sensor connected to the first proximity sensor configured to detect object movement over a plane substantially parallel to the at least one side surface of the first proximity sensor. The multi-directional movement detection proximity sensor may include a PCB, in which more than one proximity sensor may be disposed on the PCB and operatively integrated to detect multi-directional movement.
