Definitely interested in a sensor calibration video!

Thanks for your feedback, I am considering doing one. The only issue is that I need a sensor calibration kit for this badboy and they can be expensive if you want a good one.

I would also be interested in a sensor calibration video 🤩

So just to be clear, higher values means toxic? then lower means safe right?

Correct

What do those "Sensor Value" of between 9k ~ 11k displayed on the Shell output? What should be the baseline value if air is free of contaminants?

Hey Gali, it is hard to know based on the raw analog values. A calibration process would be needed for this kind of sensor to translate them to a certain contaminant value :/

Hi! I think your connection is not working because the values are not changing. When the analog sensor works, it gives values in the level of 30000 or more when hovering over bottle of alcohol. I used a Waveshsre MQ-135 and they've changed the wiring. Digital and analog pins have changed place. You probably have the same issue and you're trying to read the digital output to analog input 28.
