Rear view parking sensor set led cob 4 sensors black "gold" 18mm

The parking sensor is a device that supports parking and reversing the car. It works on the principle of sonar - it emits ultrasonic waves, which, when reflected from an obstacle, allow you to determine what distance separates the car from the obstacle. When reversing, the device correctly recognizes obstacles in the way of the vehicle and warns the driver with a sound. The LED-COB display has cob diodes that will minimize the color depending on the distance to the obstacle and indicates the distance with an accuracy of tenths of a meter. Built-in speaker (buzzer) warning of an obstacle has 3 volume modes. (jumps, low, muted) Display size: 10.5 x 1.5 x 3cm Cable length: ~5m Sensors in the "GOLD" version are smaller than standard and have an airtight connector on the cable so that we can detach the sensors from the vehicle installation in case of dismantling the bumper or damage. The latter are also equipped with metal hooks that ensure stable holding of the sensors in the bumper. The set includes: 4 detectors (sensors) black "GOLD" 18mm LED display with built-in buzzer control unit 4 sensor hole saw for drilling holes in the bumper.
