Passive Infrared Sensor Market Profit-Sources Analysis Report 2024-2033
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement but do not give information on who or what moved. A PIR sensor only detects that something moved; it cannot tell you what or who moved.
