Abstract
A sensor comprises a sensing element to generate output signals corresponding to receiving signals received from an object and an evaluation unit coupled to the sensing element and weighting the output signals from the sensing element with at least one switching threshold to generate object detection signals. The evaluation unit includes a key adapted to selectively reset the at least one switching threshold to higher and lower values through differences in activation of the key.
