1. A parking sensor device for determining occupancy of a parking space, comprising:
a magnetometer sensor configured to detect a magnetic field;
a radar sensor configured to perform at least one radar scan to detect presence of an object;
control circuitry configured to:
determine whether the object detected by the at least one radar scan includes a blocking substance near the parking sensor device, the determination comprising distinguishing detection of internal leakage of the radar sensor from detection of the blocking substance; and
determine occupancy of the parking space based on the magnetic field and the at least one radar scan as a function whether a blocking substance is detected; and
an output for conveying occupancy of the parking space.
