20180227· MQ135 gas sensor applies SnO2 which has a higher resistance in the clear air as a gassensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. To measure PPM using MQ135 sensor we need to look into the (Rs/Ro) v/s PPM graph taken from the MQ135 datasheet.

CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a ...
