Basic composition of reversing radar
The reversing radar is mainly composed of an ultrasonic sensor, a controller and a display or a buzzer.
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: The signal is processed to calculate the distance and orientation between the vehicle body and the obstacle.
3. Display or buzzer: When the sensor detects that the distance between the car and the obstacle reaches a dangerous distance, the system will send an alarm through the display and the buzzer to remind the driver.
