How to calibrate an MQ135 gas sensor (CO2) Sensors ...

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.

Presenting MQ sensors: lowcost gas and pollution ...

Feb 16, 2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
