float Ro4 = 2.511; //MQ135 2.51 this has to be tuned 10K Ohm
float RL4 = 0.990; //MQ135 FC-22
I know that CO2 PPM default is about 400 ppm. so during calibration i have to use different R0 Value right? Ro value for co2 is 41763, so i will use r0 2.511 for other gases and 41763 for co2. Can i have an advice?
thanks

I would use this for only one gas at a time, only CO2 can be available to
clean air for there is a global concentration, any other you would need a
know concentration to play with.

Im using mq135 sensor. i get these values curve.
These are R0 and RL.
