Passive smoking dosimeter

Protect you health ...
  [vote for,

A pager-sized device which continually samples the surrounding air and checks the tar/nicotine/CO content by using heated semiconductor-block sensors, or ISFETS. The unit gives an integrated reading of smoke dosage in Equivalent Cigarette Units, and bleeps an alarm if user-defined thresholds arevexceeded.

       I have a low-tech, less precise, more accurate version of this. I call it nose. Your version may work too. Logical question: why?

       //bleeps an alarm//
+ on the condition that it would "cough" instead.
Amos Kito, Jul 31 2003

       [World] - your nose may not, er, ... stand up in court. Maybe.

       Ah. The answer to my question is for lawsuits. Hmmm... You'll still have a tough time proving an unsafe dosage, but I'll bun it.
Worldgineer, Jul 31 2003

       I agree with Worldgineer. What is the purpose of telling someone that their smoking is too smokey?
crispee, Jul 31 2003

       its *passive* smoking, crispee   

       8th, I would have thought that you spend most of your time in smokey rooms <cough>

       + for the idea, and + for a new verb. To annoy through excess.

       remember that most toxic gases (e.g. CO) have no odor

       This would be bad for everyone but the tobacco companies.   

       It would put the onus of proving level of exposure on the plaintif.

       I guess I don't get it. Why not stop, point and yell SMOKE! when you see someone light up? Unless it's illegal why would anyone care if their smoke levels are too high? I think all we can do is just sit in non-smoking.
crispee, Aug 01 2003

       Or yell FIRE! as we all know there's no smoke without it.

       This is not a novel invention. It is fact exists, and is used to check all kinds of air quality issues.
