Abstract
A method for operating a sensor device for measuring a concentration of a gas species in a gas is disclosed. In an embodiment, the method includes recording a set of data points by performing a plurality of measurements of a temperature sensor element reading, wherein each of the measurements is performed with a different heater setting of the first pellistor element and each of the measurements results in a data point of the set of data points, performing a curve fit of an evaluation function to the set of data points, wherein the evaluation function comprises a first function and a second function, wherein the first function is based on an ideal behavior of the first pellistor element, and wherein the second function is a temperature-dependent steadily rising or steadily falling function and determining the concentration of the gas species in the gas from the curve fit.
