A method for operating a gas sensor device, which is equipped with at least one gas-sensitive electrical sensor resistor, a heating element for the controlled heating of the sensor resistor, a detection element for detecting the resistance value of the sensor resistor, and a signal processing element for processing measuring signals. In the method, measurements are carried out in time intervals, in which the resistance value of the sensor resistor is detected as a measuring signal, and the sensor resistor is heated for each measurement, the heating element being operated discontinuously in heating intervals and each measurement being assigned a heating interval. Measurements are automatically carried out in predefinable time intervals, and additional measurements are initiatable at arbitrary times. The duration of the heating intervals assigned to the individual measurements being selected as a function of the time interval to the preceding heating interval.

A method for analyzing a gas, where a sensitive metal oxide-containing layer is exposed to the gas, includes: reducing the temperature of the sensitive layer from a first temperature to a second temperature, the temperature of the sensitive layer being maintained essentially at the second temperature for a predetermined time period; increasing the temperature of the sensitive layer to a third temperature; measuring at least one electrical resistance value of the sensitive layer while the sensitive layer exhibits essentially the third temperature; and analyzing components of the gas based on the measured at least one electrical resistance value.
