Are PIR sensors universal?
The motion detector module is suitable for many applications where motion or presence is registered and so switching operations are caused.

What is the maximum distance to detect the PIR sensor?
Since PIR sensors have ranges of up to 10 meters (30 feet), a single detector placed near the entrance is typically all that is necessary for rooms with only a single entrance.
Is PIR and IR sensor same?
Their main differences include: The IR sensors detect whether the light from the transmitter is emitted by an object or a person. Whereas, the PIR sensors detect changes in the levels of energy around the area. PIR sensors don’t actually emit the infrared; objects give the sensor infrared rays.
Do PIR sensors work through glass?
The motion sensor is based on passive infrared detection, therefore it works through clear glass.
Why do PIR sensors fail?
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. This causes air convection inside the PIR.
Do PIR sensors wear out?
Generally speaking, PIR sensors are small, inexpensive, low power, rugged, have a wide lens range, are easy to interface with, and are easy to use. Their best feature is that they don’t wear out. PIR sensors are most frequently found in motion detector devices aptly called passive infrared detectors (PIDs).
