Zusammenfassung: | A method to provide calibration data for a gas sensor device, wherein the gas sensor device comprises a gas sensitive material electrically arranged between a first and second contact region, and a control electrode which is arranged neighboring to the gas sensitive material, wherein the resistance of the gas sensitive material has a dependency on an environmental target gas concentration and has a dependency on a control voltage applicable to the control electrode, the method comprising: exposing the gas sensitive material of the gas sensor device to different adjusted target gas concentrations of a target gas, determining measurement values of the resistance of the gas sensitive material between the first and second contact region in response to the adjusted target gas concentration, determining a first gas sensor behavior model based on the measurement values of the resistance of the gas sensitive material as a function of the adjusted target gas concentration, translating the first gas sensor behavior model into a corresponding second gas sensor behavior model for the resistance of the gas sensitive material of the gas sensor device as a function of the control voltage applicable to the control electrode, and sweeping the control voltage based on the second gas sensor behavior model over a control voltage range for providing control voltage dependent resistance data, wherein the provided control voltage dependent resistance data or data derived therefrom over the control voltage range of the gas sensor device form the calibration data for the gas sensor device. |
