Hi every one.

I am trying to make a very small smoke detector which will detect Cigarette smoke.
I found lots of different smoke detector IC's But none of them actually smell smoke by it self.
if it is possible i would want to use a ionization type detector because it works faster and also with less smoke.
it needs to be small and safe to put in the pocket.
So please can any one help me get my project done so my teacher will get impressed.

Thanks you for helping in advanced.

Smoke detector ICs do not detect smoke. They detect an electrical signal produced by the detection module.
Ionization chambers used in smoke detectors contain a small amount of radioactive material.
This is not something you can do without proper authorization from nuclear radiation regulatory bodies.
