May 05, 2021· Hi Guys, The literature that came with this kit might have well as been non-existant. I have a sensor I've wired to my arduino uno, and it looks like it's working. For instance, it typically reads around 150-200 with just the ambient air, but when I focus my butane lighter on it, it'll jump up into the 600-700 range - so I guess it's working. I assume the key figure I should look at is the ...
