Abstract
A method for operating a gas sensor device for ascertaining information about an air quality. The method includes: providing a gas sensor device including at least one gas-sensitive electrical sensor resistor, a heater for the controlled heating of the sensor resistor, a detection device for detecting the resistance value of the sensor resistor, and a signal processing device for the sensor signal; heating the sensor resistor using the heater alternatingly in a first heating mode in a first operating phase and a second heating mode in a second operating phase, each heating mode including a sequence of heating pulses so that the sensor resistor is heated at predetermined temporal intervals for a predetermined duration to a predetermined operating temperature, an essentially identical operating temperature being selected for the at least two different heating modes; detecting the resistance value of the sensor resistor and generating a sensor signal.
