how to detect smoke

Is it possible to detect smoke with atmega32?
Can anyone please give the circuit design to detect smoke using atmega32?
 

Yes. It is possible to detect smoke with Mega32. But for compactness 8pin device like Tiny13 or 15 may also be used. If the smoke detection is only the requiremnet, actually there is no need for microcontroller, instead it can be done simple with a LED and LDR arrangement. Cheers.
 

Hello,

Can you please give the circuit diagram please?
It will be helpful for me.
