Specs:
I hacked one of those dual-sensor ion/photoelectric combination alarms. It now has a telephone jack coming out the side, and a telephone wire connects it to a Raspberry Pi. This supplies dedicated power and communicates with the alarm to text me/email me/play an alarm on my phone when the detector goes off (sounds like a school siren). I can then pull up my camera feed and see what set it off. It also sends out a heartbeat signal to a central server, which will alert me if it hasn't received anything from the detector in a while.
It actually works pretty well. It's sitting right above the stove and has very very few false alarms. I could probably eliminate them entirely if I tweaked my programming a bit.
The smoke detector I used as a basis for my mods: First Alert Smoke Alarm
