The Crowtail- Mini PIR Motion Sensor is a compact, low power consumption and cost effective PIR sensor. It interfaces directly with up to two conventional PIR sensors via a high impedance different input. The PIR Signal is converted to a 15 bit digital value on chip.

It is used for making motion detecting applications such as alarm burglar systems, visitor presence monitoring, light switches and robots.
