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 ...

VST-892HD is a new generation passive infrared (PIR) motion sensor camera with enhanced transmission speed, capable of capturing high definition images (picture quality of up to 1280 x 720 pixels) to ...

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.

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 ...
