hello genius guys

i want to make FLAME DETECTOR or SMOKE detector ckt

plz can anybody help me and tell me the ckt diagram of FLAME/Smoke detector

For a simple smoke detector you could use an MC14467 ic.  Look at page five in this datasheet and it gives you a pretty simple circuit schematic; just a few external components and a piezo alarm. (The chip costs like $1.50 at digikey.com)
