hi there.
Does anyone have/know a simple circuit to detect smoke.What are the main part/detector name? or maybe it just can be done by just using a LED/IR LED and LDR that connected to NPN and a relay what so ever.
Note that, this is not really a critical project that is to really detect smoke in case of fire/emergency.No life will be harm if it fails to work : )
thanks.
