Alright, btw how do you able to get this 2 value
Ro0 = 4.300; //MQ2 3.83 this has to be tuned 10K Ohm
RL0 = 2.897; //MQ2 Elecfreacks Octopus
Can you show me the equation to find this value?

some may come from others, remember that no MQ sensor is to be relied on first, and then that no calibration can be done without known gas concentration.
only the "clean air calibration" method can be used, given you know concentration in the air around you.
