Provided is a sensor system (1) comprising a first sensor device (10) and a second capacitive sensor device (20) for detecting a movement of the object relative to a detection surface, wherein the sensor system may be operated in a first mode of operation and in a second mode of operation, wherein the sensor system may be switched over from the first mode of operation into the second mode of operation, wherein the second capacitive sensor device (20) comprises a number of second sensor electrodes (21), and wherein in the sensor system at least in the second mode of operation at least one signal path (GND, RBYPASS, PIN) connectable with a predetermined fixed electric potential (GND) is provided, which is parallel to a parasitic capacitance (CPARA) of the first sensor device (10). Further provided is a method for reducing a settling time of the second capacitive sensor device (20) for detecting a movement of an object relative to the detection surface, wherein the second capacitive sensor device is part of the sensor system (1) according to the invention, wherein at least in the second mode of operation in the sensor system the at least one signal path (GND, RBYPASS, PIN) is connected with a predetermined fixed electric potential (GND), wherein the signal path is parallel to the parasitic capacitance (CPARA) of the first sensor device. |
