Why do i need this in the first place?
well, to make things short, i have a prototype, called a smokers' quit watch. it is a digital watch with a smoke detector. It records the time the user had smoke. After we presented the prototype, we were asked to make the design detect only the smoke of a cigarette and not any smoke.
So the question is, how do we do this?
where in the philippines. if we would buy this kind of detector? how to build one for ourselves? any ideas?
