How to calibrate an MQ135 gas sensor (CO2) Arduino Forum

May 06, 2021· If you have a tank of Nitrogen or Oxygen, you can use that to get a reading for zero CO2. A quick scan of the datasheet for the MQ135 shows that it responds to a lot of gases. If someone farts nearby, it will detect it and you can''t tell which gas it was. Actual CO2 sensors cost 80400 for the cheap ones. Thanks for your help.
