Ultrasonic sensing solutions for proximity and position sensing

Ultrasonic sound waves are vibrations at a frequency above the range of human hearing (>20kHz) that can travel through a variety of mediums (air or fluid) to detect objects and measure its distance - without making physical contact. Ultrasonic sensors can be used to detect a wide variety of materials regardless of shape, transparency or color.
