This analog gas alcohol sensor on basis of hydrogen concentration has a small heating part with an electronical chemical sensor. It is suitable for indoor usage. The sensor can output exact values only after warmup phase.
Caution: sensor gets hot while usage!
100 - 1000 ppm
Ethan, Alcohol over the concentration of hydrogen
F.i. breath alcohol tester, robotic, microcontroller projects
