MQ135 Gas Sensor Pinout, Features, Alternatives ...

27/02/2018· 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.
