A sensor device for a computer system has a transceiver unit and a data processing device connected to the transceiver unit, wherein the data processing device is configured to predefine emission of signals at measuring intervals for the transceiver unit; detect, on the basis of received, reflected signals, signal ranges assignable to objects; define a deviation in intensities of the received signal ranges over a plurality of measuring intervals for associated, detected signal ranges; and decide, on the basis of the defined deviation, whether a change has taken place in the object assigned to the respectively detected signal range. |
