Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Climax Technology SD-32-H-SC-AC AC-powered smoke detector with heat detector Climax Technology VST-892LEX-HD-IL-BUS Hardwired Outdoor HD PIR Motion Sensor Camera with infrared (IR) fill light, without ...

In this YouTube video, the team from Mythbusters try to beat a thermal intrusion security sensor (a passive infrared sensor, aka PIR, that detects thermal differences). See how many attempts and what ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Home automation with high usefulness and low annoyance tends to rely on reliable person sensing, and [francescopace]’s ESPectre shows one way to do that cheaply and easily by leveraging hardware ...

Honeywell’s 5898 Wireless K-Band DUAL TEC Motion Sensor provides superior detection and reduces the risk of false alarms. The combination of PIR and K-Band microwave technologies enable the sensors to ...
