The Edwin Robotics PIR Motion Sensor is an industrial grade sensor based on the low power long range Panasonic EKMB series, it features and onboard controller and the ability to be powered over the ethernet port. The onboard controller can be reprogrammed to modify the sensitivity or even to act as an indepenet module to directly trigger a relay module.
PIR (Passive InfraRed) sensors are what is commonly used for detecting the presence of a human being (or any warm body) in its given range by detecting a change in the temperature by comparing the current and previous infrared signatures.
