1. A sensor device, comprising:
a capacitive sensor unit,
a coil unit which at least partially, surrounds the capacitive sensor unit,
a control unit, and
a physical switch controllable by the control unit to selectively turn on or turn off a sensing operation of each of the capacitive sensor unit and the coil unit,
wherein
the capacitive sensor unit has at least one first sensor element which is aligned essentially along a first geodesic of the coil unit,
wherein
the capacitive sensor unit comprises a plurality of second sensor elements for sensing a capacitive change in the environment,
wherein
the second sensor elements are arranged in a star-shaped manner,
wherein
the physical switch is controllable to turn off the sensing operation of the capacitive sensor unit when the sensing operation of the coil unit is turned on, and
the physical switch is controllable to turn off the sensing operation of the coil unit when the sensing operation of the capacitive sensor is turned on.
