A sensor arrangement for sensing movement gestures on a motor vehicle with a capacitive sensor arrangement and at least one control and evaluation device which is coupled to the sensor arrangement and which senses a change in the capacitance of the sensor arrangement with respect to a reference potential. A user can use a part of his body, for example his foot, to make a gesture in the sensing range of the sensors for activating a tailgate. At least two sensor electrode arrangements are arranged at spatially offset positions on the motor vehicle. The sensor electrodes are embodied as elongate electrode arrangements and are arranged with the same spatial orientation. One of the sensor electrodes is longer than the other. The relatively long sensor electrode extends beyond the relatively short sensor electrode on both sides in the longitudinal direction.
