The invention relates to a machine controller comprising a sensor module (4), an evaluation module (9) and a control module (5), and the sensor module (4) has a convertor which converts a mechanical variable acting on the sensor module (4) into a proportional electric characteristic variable, and the evaluation module (9) is connected via a first signal connection (8) to the sensor module (4) and via a second signal connection (11) to the control module (5). The evaluation module (9) generates a signal profile from the detected electric signal by means of an analysis of potential and/or change, which is compared with at least one reference signal profile stored in a memory means of the evaluation module (9) by means of a comparison module of the evaluation module (9), from which the control signal is generated. Furthermore, at least one of the two signal connections (8, 11) is based on a wireless design.
