Ultrasonic Parking Aid

Parking your vehicle in a narrow space is always a risk. This parking aid project from Cornell university students will help you to prevent your Mercedes from getting scratched while parking in a tight space. This ultrasonic ParKontroller can sense how far you are away from the wall or a hidden object behind your car and warn you visually and audibly using LEDs and speaker respectively.

The students use the principles of Sound Navigation and Ranging (SONAR) technique in this design. This principle is used for finding the distance and direction of a remote object underwater by transmitting sound waves and detecting reflections from it. First, a series of short ultrasonic pulses are transmitted using a transducer that changes voltage into sound waves.


This parking aid device can detect an object within a range of 40cm with accuracy of 1cm in the distance interval of 15 to 40cm. For more details, visit: Ultrasonic Parking Aid.
