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.

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 ...

PIR Motion Detectors have been present for a considerable time in building, home alarm and monitoring systems markets. A PIR Motion Detector predominantly converts a microwave signal, infra-red light ...

2GIG Passive Infrared Motion Detector, 345MHz 2GIG-PIR100-345 The 2GIG PIR100-345 Passive Infrared Motion Detector is a wall-mounted unit with wide-angle motion protection. It communicates with the ...

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, ...

Combination flame & passive infrared motion sensor with two output modes including “And” detection and “Individual” modes. Designed to minimize nuisance alarms where fast acting spark/flame may be ...
