1. A sensor system, comprising:
a rotation rate sensor including a seismic mass and being configured to drive a movement of the seismic mass using a driving force; and
a control unit, wherein the control unit is configured to detect a free fall of the sensor system and to deactivate the driving force in an event of a detection of the free fall,
wherein the rotation rate sensor includes an electrode array for generating the driving force,
wherein the control unit is configured to continuously monitor the sensor system for the free fall during a sensor operation,
wherein the driving force is deactivated by the control unit by shutting off a voltage present at the electrode array.
