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.
Traditionally motion sensors are an integral part of a home security system. These devices are typically installed to cover a large area as they commonly cover up to 40 ft (12 m), with a 135° field of vision. A type of motion sensor was used by the Japanese since ancient times.
These top-rated lights equipped with sensors that'll automatically shine a light (three of them, in fact) when they detect motion — important when you get home after dark and can't see a thing.
