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.

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

Tempe, Arizona - Southwest Microwave, a leading global supplier of perimeter intrusion detection systems, has announced the introduction of the advanced Model 420 Passive Infrared (PIR) Sensor for ...

Texas Instruments recently brought to market what it claims to be the world's first single-chip passive infrared (IR) micro-electro-mechanical system (MEMS) temperature sensor, called the TMP006.

Pyreos, a developer of passive infrared sensors based at the Scottish Microelectronics Centre in Edinburgh, is set for expansion after securing $4 million in a venture funding round. The latest ...
