Scanning of a motor vehicle footprint

A park sensor for sensing a motor vehicle on a footprint is adapted to be mounted in the space and comprising: a radar sensor for sensing the motor vehicle; a wireless interface; and processing means which is adapted to provide a first signal over the wireless interface if the motor vehicle has been detected by the radar sensor in the region of the footprint. Further, the processing means is adapted to determine by means of the radar sensor at a distance to the motor vehicle and to provide a second signal indicative of the distance.
