Interfacing of MQ-135 Gas Sensor with Arduino

Interfacing of MQ135 Gas Sensor with Arduino: In today’s world, we encounter different scenario where we see different gasses being emitted in atmosphere such as home appliances like air conditioner and industrial chimneys. Monitoring of these gasses is very important with safety point of view. Gas Sensors are very helpful in accomplishing this task.

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

27-02-2018 · 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 …
