What is an Infrared Detector?

An infrared detector is an electronic sensor that detects infrared radiation emitted by objects. Since every object above absolute zero emits infrared energy, these detectors can identify temperature differences without physical contact.

Infrared detectors convert thermal radiation into electrical signals, enabling devices to produce thermal images, detect motion, monitor temperatures, and identify objects in complete darkness or adverse weather conditions.
