A low cost pulsed laser that draws air through the the beam with an LDR behind the laser feeding a simple AC amplifier will detect smoke particles and if you have it dust...

The cigarette smoke contains carbon monoxide so you will need a carbon monoxide sensor.You can can buy it from sparkfun.com.Also checkout the wiring example.Experiment with the sensor get the readings using a arduino or any microcontroller and make one yourself

You want to make yourself ? It' s difficult ,the plastic and many others kinds of parts.

The airlines use normal smoke detectors which use the ionisation properties of smoke to set off the detector.

The question is, how dilute can the smoke you want to detect be?

If sufficiently dense to be seen, the old optical detector approach would work.

If less dense, a commercial smoke detector may be your best best.

If _very_ thin -- if at a level which wouldn't set off a fire-safety smoke detector.-- you're into lab equipment with costs to match.

Smoke detectors are very hard to make as they normally contain radioactive materials, which are not really safe to handle. Cigarette smoke sets off standard smoke alarms, which should help you with your project.


As different to any other kind of smoke?
