Abstract
Disclosed herein is a gas sensor that includes a sensor part configured to generate a gas detection signal in accordance with a concentration of a gas to be measured, and a control circuit configured to generate an output signal indicating the concentration of the gas to be measured based on the gas detection signal. The control circuit is configured to correct the output signal so that the output signal indicates a concentration of the gas to be measured higher than that indicated by the gas detection signal when a level of the gas detection signal output from the sensor part is less than a reference value corresponding to a level of the gas detection signal which is normally obtained when a concentration of the gas to be measured is a concentration value in normal time.
