Nice one! This is a project im working on as well... what kind of IC did you use for the smoke detector? I guess its an optical detector one since you have a smokechamber.
I am still using several temp/hum sensor and they are running great I also have just added code and pictures for my newly build light sensor (using an LDR).

The only downside is (1) price and (2) it cannot be used with batteries
For these factors alone, the Figaro looks very appetizing.
