FAQ

1. passive infrared motion detector?

Five Causes of PIR False Alarms. The first cause of PIR false alarms is low or unstable voltage at the detector. Test to make sure the voltage at each PIR is above 13VDC and stable. The second cause of false alarms is sudden infrared movement / heat changes in view of the detector.

When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves.
