Ultrasonics have been used for decades in a wide variety of industries. Ultrasound is a sound pressure wave that oscillates at a frequency higher than that of audible noise. For our application, ultrasonic transducers were used in conjunction with the Altera DE2 development board to create a accurate rangefinding system. The transducers can be set up side-by-side to detect the distance of other objects or, for increased range demonstrations, set up across from one another pointing at each other.
