arduino uno Preheat time required for MQ5 gas sensor ...

After those 24 hours it can be used in a normal way and it will return consistant values. The preheat should be done just once. I mean: just once in the lifespan of the sensor. After buying it, you should run the preheat. When the manufacturer writes in the datasheet that the preheat time is 24 hours, then you should do 24 hours.

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. The above figure shows shows the typical sensitivity …
