Working principle of the product:
When the product is working, the sensor emits ultrasonic waves. When encountering an obstacle, the ultrasonic waves are reflected. The sensor receives the reflected signal and transmits it to the control box. Through calculation, the control box obtains the distance between the vehicle and the obstacle, and reminds the driver to pay attention through the display and sound, etc., to avoid danger. It is a good helper for us to drive the car!

The display has 2 values, representing the danger distance in front of the car and behind it! If you choose a product with 4 sensors, you will only get the value behind the car.

The display has 3 buttons, which can adjust 4 alarm sounds (buzzer/voice/mute/buzzer+voice) and the size of the alarm volume

The display cable is separated, which is easy to install
