The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

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 ...

When intelligence-gathering matures from finding and following an individual or vehicle to monitoring entire groups to understand their intent, the narrow, “soda straw” field-of-view of conventional ...

As the U.S. Army produces third-generation forward-looking infrared (FLIR) sensors, officials are exploring emerging capabilities that might be integrated into fourth-generation systems. FLIR ...
