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.

One of the innovations gaining traction in recent years is touchless toilet technology. Designed to eliminate the need for ...

The video demonstrates how to wire up a Passive Infrared Sensor (PIR) using 4-core security cables. All Gallagher inputs are balanced 4-state inputs and must have two 4k7 resistors wired at the device ...

Particulate content in the air? There’s a sensor for that, too. Someone sneaking up on you? Get yourself some passive infrared sensors (PIRs) and maybe a smart camera just to be sure.

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.

EarthTronics, dedicated to developing innovative energy-saving lighting products that provide a positive economic and environmental impact, introduces EarthConnect Area Light sensor for Luminaire ...

This new system, named IRST21, is a long-wave infrared search-and-track sensor that allows for the passive detection of airborne threats at extended ranges, far surpassing visual capabilities.
