Abstract

Various arrangements for determining that a vehicle is present in a parking space are presented. A parking sensor can make a plurality of magnetic field strength measurements using a magnetometer. The magnetic field strength measurements are analyzed to determine a number of the plurality of magnetic field strength measurements that are within various magnetic field strength windows A magnetic field strength window may be selected as a vehicle-detection baseline. A determination that the vehicle is parked proximate to the parking sensor device within the parking space may be made based on a magnetic field strength measurement being outside of the selected magnetic field strength window.
