Electronic – MQ-135 Gas Sensor Interface – iTecTec

From the MQ-135 Datasheet you can see that the sensing resistance is 2 kΩ to 20 kΩ and the test circuit shown is really just forming a voltage divider from the 5 V supply with the lower end being R you select R L as kΩ when the sensor resistance is 2 kΩ the output will be V and when it is 20 kΩ it will be 708 mV which you can directly connect to your ADC.
