Passive infrared (PIR) motion sensors are electronic devices designed ... it triggers a change in the detected infrared energy pattern, resulting in the generation of an electrical signal.

The pattern includes long ... eliminates the detection ‘dead zone’ characteristic of traditional passive infrared sensors,” explained Bob Kirkaldie, Southwest Microwave’s Director of ...

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 ...

[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 ...

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 ...

Traditional motion sensors have long relied on Passive Infrared (PIR) technology ... enabling adjustments to the sensor’s field pattern and aesthetic appearance to suit specific application needs.

Get yourself some passive infrared sensors (PIRs) and maybe a smart camera ... a characteristic V-shaped drop in current is observed; this pattern shifts as pressure changes, allowing the system ...

A trial of outdoor, wireless passive infrared sensors (PIRS) could lead to more deployments in ... while the FTN-R sensors provide a shorter detection range in a curtain-like pattern. Combining the ...

and IoT devices that typically use passive infrared (PIR) sensing. The STHS34PF80 sensor contains thermal transistors that can detect stationary objects, unlike conventional PIR detectors that ...
