'MySensoring' a Kidde Smoke Detector.
« on: February 08, 2015, 03:12:53 pm »
Hardware wise this project is VERY easy to complete. The hardest part was arranging the hardware to fit in the case. The sketch on the other hand was a pain in my butt and I'm sure it's VERY inefficient,  but does seem to work without ANY false alarms.

Thanks to BulldogLowell for the coding help!

Mod Goals:
1) Detect when the siren is powered up and transmit that "trip" to Vera (for various processes)
2) Use interrupt to start Arduino with a 9 hour "heart beat".
3) Utilize the detectors battery power.

Because this detector has on-board battery level checks and warnings, I don't have to mess around with building a battery circuit.

BOM:
1) Pro Mini
1) I'm using Optocoupler for the speaker power isolation (you could probably just sense the 3.3v speaker voltage directly).
1) Kidde Detector Used (any can be used providing you have the space inside)
