The gas-sensitive material used in the MQ-135 gas sensor is tin dioxide (SnO2) which has a low conductivity in clean air. Having different resistance values for different concentrations, the change in conductivity can be converted to an output signal corresponding to the concentration of that gas using simple circuitry.With high sensitivity to ammonia, sulphide, and benzene vapours, and ideal for monitoring smoke and a wide range of other hazardous gases, the MQ135 sensor is a low-cost sensor suitable for a wide range of applications.
