Interfacing of MQ135 Gas Sensor with Arduino

The sensor needs a loadresistor at the output to ground. Its value could be from 2kOhm to 47kOhm. The lower the value, the less sensitive is the sensor. The higher the value, the less accurate is sensor for higher concentrations of gas. If only one specific gas is measured, the loadresistor can be calibrated by applying a known concentration of that gas. If the sensor is used to measure any ...
