The invention relates to a sensor array for detecting the approach and movement gestures of a user at a motor vehicle, comprising a capacitive sensor array (2, 3) and at least one control device (5) that is coupled to the sensor array and detects a change in the capacitance of the sensor array. The sensor array comprises at least two sensor electrode arrays (2, 3), which are arranged at spatially offset positions on the motor vehicle, the sensor electrodes (2, 3) being configured as elongate electrode arrays and being arranged with the same spatial orientation. The control and evaluation device is designed for cyclical activation and evaluation of the sensor electrodes with changeable, electrode-specific, different cycle rates.
