How reversing radar works?

Reversing radars adopt the principle of ultrasonic distance measurement. When the driver reverses the vehicle (the gear shifts to the R position), the system starts to emit ultrasonic waves from the probe at the rear of the vehicle to the rear of the vehicle, generates echo signals after encountering obstacles, and controllers. After the echo signal is controlled and processed, the direction and distance of the obstacle are determined, and finally, the buzzer emits the voice prompts to make the driver reversing his/her mind, easier and safer.

Product function description:

The system automatically enters the detection working state when the reverse gear is engaged.

30CM-250CM centimeter display accuracy, accurate display obstacle distance.

Sound step by step alarm, the closer the distance, the more rapid the alarm sound.

Double CPU response quickly. Probe self-test function, probe abnormal state prompts, to avoid reversing collision due to probe damage.

Embedded probe installation, installation is simple and convenient.
