#65621 Hi there,

I just published a small story on my weblog in which I describe a Proof of Concept for an alarm made with a PIR sensor that sends a twitter message when someone enters your room.

Most alarms just make noise. That looks efficient but what if you are not at home. You will not hear the noise.
My alarm send a twitter message that can be seen from anywhere in the world.

Electronics is simple and I made a casing for it.
