Door Alarm

Hacked Gadgets Forum member Alexander125 from Romania is using his ioBridge IO-204 to help him secure his house.

I’ve been recently working on a sistem to keep my house safe while I’m away.Using the IO-204 module I’m building a simple sistem to monitor power consumption in the house, movement(if there is any) using PIR motion sensors and the doors or windows.
For the interface with the IO-204 I decided to go cheap and make myself some adaptors using perfboard, some connectors and a bit of solid-core 22AWG wire.
For the power consumption, I wanted to put a clampmeter on the wires carying power to my apartment and tap into the circuitry to tell me when the amperage passes over a specific threshold.
