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. A determination that the vehicle is parked proximate to the parking sensor device within the parking space can be based on a magnetic field strength measurement in relation to the selected magnetic field strength window.
