Rear view parking sensor set led cob 4 sensors black internal 16.5mm

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 new sensors are mounted on the inside of the bumper and do not protrude beyond its outline. The small size makes them look very attractive. The sensors can be painted. It is recommended to apply a maximum of two thin, even layers of varnish. 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.
