Overview
The parking sensor is a safety assistance device when the car is parked or reversing. It can inform the driver of the surrounding obstacles by sound or a more intuitive display. It removes the driver’s parking, reversing, and left and right visits when starting the vehicle. It bothers and helps the driver to eliminate the blind spots and blurred vision. [1]
basic component
Parking sensor is mainly composed of ultrasonic sensor, controller and display or buzzer, etc.
1. Ultrasonic sensor: The main function is to send and receive ultrasonic signals, and then input the signals into the host and display them through the display device.

2. Controller: Processes the signal to calculate the distance and orientation between the vehicle body and the obstacle.
3. Display or buzzer: When the sensor detects that the distance from the vehicle to the obstacle reaches a dangerous distance, the system will send an alarm through the display and buzzer to remind the driver.
working principle
The reversing radar uses the principle of ultrasound when reversing, and the probe installed on the rear bumper sends an ultrasonic wave to hit the obstacle to reflect the sound wave, calculate the actual distance between the car body and the obstacle, and then prompt the driver to stop or Reversing is easier and safer.

The main function
(1) Accurately measure the distance between the rear of the car and the nearest obstacle;
(2) When reversing to the extreme distance, a rapid warning sound can be issued to remind the driver to pay attention to braking;
(3) Voice warning sounds can be repeatedly issued to remind pedestrians to pay attention
