Nice work.

It looks like you're well into the fundamental parts and the bits with a longer lead time ...well done.

Interesting sensors and the relatively cheap prices.

The video of you testing MQ-3 should be worth a watch.

Great rundown on the sensors.

Are these all available as a kit or do you need to buy them selectively?

Hi Douglas [mention:193ac2434c814a24b46635a2210baec1:e9ed411860ed4f2ba0265705b8793d05]

I really like this project, the way you are having multiple sensors checking many different gases should make it extremely accurate. I see most hazardous gases have 2 - 4 sensors checking for each one, so if one misses the hazardous gas, another will catch it. This system will be useable anywhere, not only industrial. Will you make it able to check blood alcohol level through a breath test?
