I am looking for a circuit which will activate an alarm when heat or moisture is sensed. Could you please point me in the wright direction :?
 
Heat *and* moisture alarm? not at the same time I assume? Or is this for a sauna :D ?
There are lots of heas sensitive switches on the market, there are also moisture sensors, you just need to adapt them to your alarm input.
good luck
