Great idea, like the way you've doubled the function of the smoke detector by utilising the space.

Is that a hardwired smoke detector? I am looking for a hardwired solution that utilizes/runs off the power from a hardwired connection. Not sure if I would have access to 3.3 volts to run the Pro Mini and radio.

not all hardwired. its a 9 volt cheap smoke detector. the chip on those have a data output that give the status of the smoke detector.
i tested on 5 volt and it works.. there is only a low voltage detection on it, but by removing R10 (100ohms) it will get turned off
only 4 wires goes from the smoke detector to the atmega (data and test, 5 volt and gnd)
final only 5 volt goes to the "smoke detector" to power the atmega and the smoke detector. from 5 volt ill make a 3.3 volt by using a 78l33 for the radio

Great job!
I work on the same project and it looks like the same detector. Can you show us a short tutorial? Or at less the code you used?
-
Can you give the name of this unit?
WHere to buy it with what price?
-
Could you share schematics, sketches? I may be intrested in building a similare device.
