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.

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, ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

[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 ...

U.S. Army Oshkosh PLS A1 resupply vehicles already have experimented with Autonomy Kits for large convoy resupply as part of the Expedient Leader Follower (ExLF) program Unmanned vehicles are expected ...

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.

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

With energy bills soaring and the cost of living ever increasing in the UK, consumers need optimum control over their lighting solutions. BLT Direct are offering Brits the chance to control exactly ...

Infrared Search and Track (IRST) systems use passive infrared sensors to detect and track targets by their heat signatures—no radar emissions, no detection—and excel at spotting stealthy aircraft. But ...
