Example Projects

A simple room greeter that plays the super mario brothers theme music when triggered by a PIR in a hacked airwick freshener unit.
A home-made security system using PIR sensors (which is built into a Start Trek panel!)
PIR sensor + Arduino + Servo = automatic cat door!
A 2-PIR motion tracker by Lucky Larry
An interesting hack whereby the PIR sensor is used 'raw' to track movement.
