Abstract
Ultrasonic distance measurement has received considerable attention in the recent past, several distance measurement algorithms have been proposed as means to get distance of different objects precisely. With the advancement of technology several methods and techniques has been proposed i.e. TOF (time of flight), TFCW etc. In this project, we used MFCW Multiple Frequency Continuous Wave ultrasonic range system, medium of waves is air. This system is based on Radio Frequency distance measurement rather than air based TOF method. The method presented here is based on comparative phase shifts generated by the three different frequency continuous waves but closely spaced. It is high resolution low cost effective and precise technique with a precision up to ±0.05m.
