Features & Specifications
If you have problems parking then this kit is for you. Using (ultrasonic) sound waves, whose frequency is
beyond our range of hearing, we can "measure" a distance. Consequently, a sensor mounted at the back of
the car can give an indication of the distance between your car and the car parked behind you or other
obstacles (only at the same height as the sensor). When the preset minimum distance is crossed, an audible
signal is generated.
