Do you need to use a Microcontroller or just sensors ?

You can make a "Heat detector" using the LM35 - Temperature Sensors.
I dont know anything about smoke detectors though but you can get a real smoke detector , open it and see how its working...
 
Ok i didnt explain what im doing (tired ;) )


(this is what ive been TOLD! to do)

There is a bulb , next to this an LDR when the smoke dimmers the light this will trigger an alarm (which needs to be turned off)

Ive been told to use a COB and an IDA2002 to make the alarm sound

But they didnt say what sort of COB , and the IDA2002 is just an amplifier im pretty sure that you can get COBs which do the lot
 
What is a COB? All you need is a comparator and something to drive the alarm, if the comparator is not able to drive it direct. I suggest you post your circuit here and ask for comments.
