MQ-135 Gas Sensor Pinout, Features, Alternatives ...

2018-02-27· How to use MQ-135 sensor to measure PPM. MQ-135 gas sensor applies SnO2 which has a higher resistance in the clear air as a gas-sensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. To measure PPM using MQ-135 sensor we need to look into the (Rs/Ro) v/s PPM graph taken from the MQ135 datasheet. The above …
