KSR Electronics supplier Migatron Corp, offer a wide variety of high-quality standard ultrasonic sensors and controllers, as well as design assistance for semi-custom units.

Ultrasonic sensors are based on measuring the properties of sound waves with frequency above the human audible range. They are based on three physical principles: time of flight, the Doppler effect, and the attenuation of sound waves. Ultrasonic sensors are non-intrusive in that they do not require touching their target, and can detect certain clear or shiny targets otherwise obscured to some vision-based sensors. On the other hand, their measurements are very sensitive to temperature and to the angle of the target.

They typically operate by generating a high-frequency pulse of sound, and then receiving and evaluating the properties of the echo pulse.

Three different properties of the received echo pulse may be evaluated, for different sensing purposes. They are:

  • Time of flight (for sensing distance)
  • Doppler shift (for sensing velocity)
  • Amplitude attenuation (for sensing distance, directionality, or attenuation coefficient)

Ultrasonic sensors are used for range of measurements, when difficult environments, challenging reflection surfaces or the need for extreme accuracy render traditional optical sensing devices unsuitable.
