How To Use MQ-135 Gas Sensor - Codrey Electronics

Jul 05, 2020· yassin: RLOAD 10000 is for 1oK Load Resistor! As clearly pointed in this post, while using the “MQ-135” library-supported Arduino setup, the gas sensor calibration can be done at 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/(sensorValue * (/))-1)*RL.
