Working principle of reversing radar
The working principle of reversing radar is very simple, it consists of three parts: ultrasonic sensor, controller and buzzer. When working, the ultrasonic sensor emits ultrasonic waves to the outside and reflects back after the ultrasonic waves hit the obstacle, which is received by the ultrasonic sensor again, while the controller calculates the distance between the vehicle and the obstacle according to the time of ultrasonic wave emission and return, and finally alerts the driver with a sharp alarm sound through the buzzer.
