1. Sensor device for detecting at least one physical variable, said sensing device comprising:
a housing,
at least one sensor element arranged in the housing,
at least one circuit board arranged in the housing and comprising a circuit arrangement,
at least one input device arranged on the housing for carrying out input operations which are processed in the circuit arrangement to influence the sensor properties,
wherein the at least one input device, to realise a touch-sensitive effect, comprises an actuation area, which is arranged on a housing wall and is permeable to electric fields, and a capacitive area, which is arranged on the circuit board or is formed as part of the circuit board,
wherein the circuit board is arranged in the housing such that the capacitive area lies directly below the actuation area,
wherein the capacitive area is arranged on an edge of the circuit board and the circuit board is arranged perpendicularly to the actuation area such that the edge of the circuit board and the capacitive area arranged therein lie below the actuation area, and
in that the capacitive area is realized on the edge of the circuit board by metallisation of the edge of the circuit board.
