Performing as a proximity sensor or in limited gesture-recognition applications, the latest version of the Electric Potential Integrated Circuit (EPIC) sensor is specifically tailored to detect movement. It is optimized for security, switching, and gaming applications. Detecting changes in the electric field, the EPIC sensor provides an output to a relay to act as a simple non-touch electric switch. It can be used in both proximity mode or to detect specific kinds of movement as a limited gesture recognition device. As the EPIC sensor does not need line of sight and detects movement through walls, it can also be used to replace, or as an adjunct to, a passive infra-red (PIR) sensor in a variety of applications.
