A sensor device. The sensor device includes a housing component with a gas-tight internal volume, at least one electrode structure arranged in the internal volume in an adjustable and/or bendable manner, at least one counter electrode fixedly disposed on and/or in the housing component, and an electronic device configured to apply an electrical excitation voltage signal between the electrode structure and the counter electrode such that the at least one electrode structure is set in an oscillating motion relative to the housing component. The electronic device is configured to detect and/or determine the internal pressure in the internal volume and/or a change in the internal pressure while taking into consideration at least one sensor signal, which is dependent on an electric voltage or capacitance between the electrode structure and the counter electrode.
