PIR Controlled Mains Power Switch

PIR Controlled Mains Power Switch

Ref Silicon Chip February 2008
You’ve seen those lights fitted with PIR detectors that turn on when someone approaches. Well now you can do the same thing with just about any mains-powered device you like. You can use it to activate security systems, decorative lighting, fountain pumps or commercial advertising etc. Just about anything that can be plugged into a standard power point can be triggered by people moving in the vicinity of the passive infrared detector. The system uses a standard PIR to safely turn on 240VAC mains device(s) for an adjustable pre-set period. It’s compact, easy to build, and will cost you much less than commercial PIR-triggered switches with similar features. Kit supplied with case, screen printed PCB, and all electronic components.
