Abstract
A sensor device for a motor vehicle includes a multi-layer circuit board on which a plurality of metallized planes are formed. A capacitive sensor electrode is formed on one of the planes for detection by capacitive approachment sensing. A control device controls the sensor electrode as a capacitive sensor electrode in order to detect approaches of a user towards the sensor electrode via an evaluation device. At least one planar electrode region is formed on each of the metallized planes, wherein each of the electrode regions is coupled to the control device. At least two of the electrode regions on different metallized planes are activated and evaluated as sensor electrodes and at least two of the electrode regions on different planes are activated and evaluated as the ground in a temporally offset manner.
