What is a pir detector

A PIR -based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically- activated lighting systems. When the sensor is idle, both slots detect the same . For that reason they are commonly found in appliances and gadgets used in homes or businesses.

Not all motion sensing PIRs are the same. Infrared intrusion detector ( sensor ) mainly including Active Infrared Detector (AIR) and Passive Infrared Detector ( PIR ), from the principle of working theory, active infrared infrared are using dual beam transmission as structure, one side with transmitt. Motion sensors can have combined features in an attempt to reduce false alarms. Since each operates in different areas of the spectrum, and one is passive and one is active, Dual Technology motion sensors are not as likely as . Passive infrared sensor can be used to detect presence of human beings in its proximity.
