The geomagnetic detector is a key part of the data acquisition system. The performance of the sensor plays a decisive role in the accuracy of the data acquisition system. The geomagnetic detector adopts a sealed design and is placed underground in the parking space. It uses a three-axis sensor to detect changes in the magnetic field to determine whether there is a parked vehicle in the parking space.
