Abstract
A computer-implemented method for operating a sensor system having at least one MEMS gyroscope and at least one pressure sensor. The method includes: receiving pressure sensor data from the at least one pressure sensor, wherein the pressure sensor data represent an ambient pressure of an environment of the sensor system; ascertaining a pressure change in the ambient pressure based on the pressure sensor data, wherein the pressure change comprises a predefined change profile; ascertaining, based on the pressure change with the predefined change profile of the ambient pressure, that the sensor system is in a falling state; and interrupting actuation of the MEMS gyroscope. A sensor system is also described.
