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.
The O2 sensor (also known as the oxygen sensor) is one of the key components in helping your car run efficiently.
