Marijuana detector module
-
Here is an off-beat idea for a my sensors project, a hotel, school, college or parents wish to detect the use of marijuana in an area. It has apparenttly been done before (http://www.dailymail.co.uk/sciencetech/article-2815802/The-MARIJUANA-smoke-alarm-Device-knows-exactly-smoking-report-authorities.html) but what module / how would we get it in MySensors?
Could it be as simple as modifying the gas module to look for the marijuana smoke signature?

Think you'd need something a bit more sophisticated than the standard MQ module. But my knowledge of how the sniffers work (used on airports to detect explosives) is low.

What's wrong with a few herbs?

I guess that might need deep calibration...

there must be something out, spectographic mass analysis was the way, reflectivity for the fields, but in air this must be some particle siez for the MQ like so I'd rather say clever manufacturing and calibration

Maybe he just wants to change the lights, music etc. in his living room to get a more fitting scene for his current activities?

Calibration is the key, now find someone who is willing to blow some smoke in your sensor

Some years ago I found an add for a Holy Herb detector chip (lost the paper though). I guess it was at the beginning of the same month as this thread
