Abstract: A sensor module includes a sensor configured to sense gas in air, a load resistor connected to the sensor, and a processor configured to determine a gas concentration of the gas in the air based on an internal resistor of the sensor and the load resistor. The processor is configured to obtain an electrical conductivity change amount of the sensor and adjust a load resistance value of the load resistor based on the electrical conductivity change amount.
