Abstract

A sensor device described having a sensor, in particular an ultrasound sensor, having a generating and detecting arrangement to generate and detect waves, in particular sound waves, the detection arrangement converting received waves into electric signals, and the electric signals being evaluable by an evaluation unit. A function-monitoring device is configured to determine an impedance characteristic curve of the sensor as a function of an excitation frequency is provided. Also described is a method for operating the sensor device.
