Set of parking sensors reversing led cob 4 sensors silver amio-02282

The parking sensor is a device that supports parking and reversing a car. It works on the sonar principle - it emits ultrasonic waves, which, after reflection from an obstacle, allow you to determine the distance between the car and the obstacle. When reversing, the device correctly recognizes obstacles on the vehicle's path and warns the driver by signaling with a sound. xa0The LED-COB display has COB diodes that change color depending on the distance to the obstacle and indicates the distance with an accuracy of tenths of a meter. The built-in speaker (buzzer) that warns about the obstacle has 3 volume modes.
