1. A sensor system, comprising:
a chip arrangement including a sensor and an acceleration sensor; and
a processor circuit configured in such a way that:
one or multiple temperature-dependent variables and/or properties of the sensor are ascertained, and
an offset of a signal of the acceleration sensor induced by a temperature gradient is corrected with using the one or the multiple ascertained temperature-dependent variables and/or properties of the sensor,
wherein the chip arrangement includes an ASIC structure,
wherein the ASIC structure includes an integrated temperature sensor configured to measure a temperature of the ASIC structure to thereby ascertain the temperature gradient between the chip arrangement and the ASIC structure.
