MQ135 Gas Sensor Pinout, Features, Alternatives ...

· 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.

MQ Gas Sensors | Gas Sensors ? IoTbyHVM Bits Bytes ...

· The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. They can be calibrated more or less (see the section about “Loadresistor” and “Burnin”) but a know concentration of the measured gas or gasses is needed for that.
