The PIR Motion Sensor is our most cost effective and maintenance free sensor. There are no reflectors to line up, just point it towards the trigger area and you're ready to go. It works by detecting the motion of body heat, making it immune to artificial fog that can sometimes confuse other types of sensors.

NOTE: This sensor has a normally-closed output contact which will work fine with any of our controllers, but may not work correctly if you are intending to use it with another manufacturer's product.
