Abstract: A gas sensor including a gas sensing device having a resonant frequency that varies with adsorbed chemicals, a frequency detector configured to detect the resonant frequency of the gas sensing device, a calibrator configured to generate current calibration data based on the resonant frequency of the gas sensing device which has been heated to a calibration temperature in a calibration mode, and a compensator configured to adjust an output value of the frequency detector based on the current calibration data in a sensing mode may be provided.
