AMN31112J (PANASONIC)

The AMN31112J is a high-sensitive human detection PIR Motion Sensor with built-in amplifier. NaPiOn series are simplified circuitry with fully integrated circuit design. Reduction of current consumption allows battery life to be extended for battery driven products, including wireless based and low power consumption devices. The entire circuitry is enclosed in a metal package, which means it has high electromagnetic shielding capability. A short focal length is all that's required even when detecting at the same distance, which means both downsizing and high sensitivity are achieved.
