The present invention relates to a method and a device (1) for predicting an end temperature (46) of a temperature change affecting a temperature-sensitive system, such as a sensor system (2). The method comprises the steps of inputting at least one measured temperature value (11) into a first temperature prediction model (30) and into a second temperature prediction model (32), calculating a first predicted temperature (34) based on the first temperature prediction model (30), calculating a second predicted temperature (36) based on the second temperature prediction model (32), and calculating a final predicted temperature (18) from the first predicted temperature (34) and the second predicted temperature (36). The final predicted temperature (18) can be calculated before the end temperature (46) is measurable by a temperature sensor (10). Thereby, limitations caused by heat-transfer-related thermal inertia are mitigated and time delay is minimized. By combining the results of two temperature prediction models (30, 32) into the final predicted temperature (18), the inventive method further can achieve a higher accuracy than a method employing only one of the prediction models. The device (1) comprises means for performing the inventive method. Further, the present invention relates to a sensor system (2) comprising the device (1).
