Set of reversing parking sensors led cob 4 sensors black "gold" 18 mm amio-02284

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. xa0 The 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. (high, low, muted) Display size: 10.5 x 1.5 x 3cm Cable length: ~5m xa0 The "GOLD" version sensors are smaller than standard and have a hermetic connector on the cable, thanks to which we can disconnect the sensors from the vehicle's installation in the event of dismantling the bumper or damage.
