Breathalyzer - Experimenting with Failed Prototyping using MQ3 Gas Sensor

I have an vested interest in playing with breathalyzers to learn exactly how they work and to personally discover what calibration procedures are needed to work properly AND accurately, as such a product would need to be used in a wide variety of field conditions. This is my journey into that discovery process that may lead to the ultimate top secret project that is "really" on my mind. If you have something to add to my findings and/or discovery, I would like to hear from you. ~Steve

To convert ppm to %vol just take [(ppm value)/10K] ie. if you have 5000 ppm then take 5000/10000=0.5%vol and that's alcohol percentage

Nothing going on in here :(

I read the thumbnail as "failed breathalyzer test" at first.
