Working Principle

The frame and shell of a car are made of ferromagnetic material (various types of steel), which make disturbance to surrounding magnetic field. According to this characteristic, the parking sensor determines whether there is a car in the parking space by sensing the magnetic field change. With build-in dual-sensors (geomagnetic sensor and microwave sensor), powerful signal analysis and processing algorithm, the detector offers enhanced information, especially acquire complementary and optimization to the reverse sensitivity characteristics of chassis with different height. 

Compared with traditional device with single sensor, TBS-201 can greatly improve the detection accuracy and reduce information loss. The detection mechanism is show as below.

  • Geomagnetic sensor detects the magnetic field lines which distorted by ferrous metal of the vehicle, magnetic field strength obtained as the vehicle presence and movement with the magnetic sensor.

  • Microwave Radar module emits wireless modulation wave and receives the reflective signals to determine if the parking spot is occupied and vacant
