2 DO200 Function Introduction (working mechanism)

This product adopts the method of geomagnetic + ultrasonic to detect whether the parking
space is occupied, which greatly improves the accuracy. The following describes the default
parameters, working mechanism, principle, and quick usage of this product.

2.1 Default Parameter Settings

Self-test interval
Note: The above parameters can be modified by commands through the serial port (TTL) or the
platform.
2.2 Detecting the occupancy of parking spaces through
Geomagnetic
By detecting the change in the strength of the magnetic field, it is determined whether the
parking space is occupied. The default detection interval is 10s.

2.3 Detecting the occupancy of parking spaces through Ultrasonic

The distance from the device to the bottom of the vehicle is detected by ultrasonic waves to
determine whether the parking space is occupied. The effective distance is 0-50cm, in which the
parking space is considered occupied, and other cases indicate that it is not occupied. The
default detection interval is 10min.
