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.

Researchers at Northeastern University have developed a next generation smart sensor for the Defense Advanced Research Projects Agency (DARPA) that is capable of identifying infrared (IR) wavelengths ...

The search for an infrared (IR) sensor that is uncooled, easy to mass-produce and capable of generating high-quality images has driven military-funded research for decades. It has been generally ...
