Abstract
A method for detecting a gas quantity of a predetermined gas by a sensor having a sensitive layer configured to measure a plurality of gases, having an impedance Zs and a heating layer, the method include a step of supplying the heating layer with a voltage ramp defining a linear change in the supply voltage between a low voltage value and a high voltage value to modify the temperature of the sensitive layer during a variation period, a step of measuring variations in the impedance of the sensitive layer at a plurality of temperatures of the sensitive layer during the variation period, so as to detect a plurality of gas quantities, and a step of comparing a variation of the impedance at a given temperature of the sensitive layer to associate the gas quantity measured with a predetermined gas.
