How To Use MQ-135 Gas Sensor - Codrey Electronics

05/07/2020· You’re free to use the AO output of your MH-135 Chinese module as well, but you might need to change its load resistor to 10KΩ (or much better 22KΩ). While using the library-supported Arduino setup, MQ-135 gas sensor calibration is done at first by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL-1)x RL, that means Rs = (5V ...
