Abstract
A gas detecting method includes heating a gas detector, formed of a gas sensing layer and an adsorption layer, for an oxygen adsorption period tat an oxygen adsorption temperature T; heating the gas detector for a target gas adsorption period tat a target gas adsorption temperature Tat which a target gas is adsorbed to the adsorption layer, heating the gas detector for a target gas desorption period tat a target gas desorption temperature Tat which the target gas adsorbed to the adsorption layer is desorbed to move to the gas sensing layer; and calculating a gas concentration of the target gas from a sensor resistance of the gas sensing layer. A gas detecting device includes the gas detector and a drive processing unit configured to carry out the method.
