Rear view parking sensor set led 4 sensors white

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 display indicates the distance from the obstacle with an accuracy of tenths of a meter. It also has a built-in speaker (buzzer), warning with the possibility of complete muting with a switch on the housing.
