- Usually, the parking sensor consists of an ultrasonic sensor (commonly known as a probe), a controller, and a display (or buzzer).
- The reversing radar generally adopts the principle of ultrasonic ranging. Under the control of the controller, the ultrasonic signal is transmitted by the sensor. When an obstacle is encountered, an echo signal is generated. After receiving the echo signal, the sensor performs data processing and determines by the controller. The position of the obstacle, the distance displayed by the display and other warning signals, and timely warning, so that the driver can know how for reversing when reversing, making the reversing easier.
- The buzzer is used for alert the driver with different sounds. This is the real beginning of a reversing radar system. When reversing, if there is an obstacle at 1.8 meters,1.5 meters behind the car, the buzzer will start working.
