An Ultrasonic Sensor works based on the properties of the sound waves with frequency greater than that of the human audible range. Operating Principle. Since the speed of sound is known, the time between the sound burst and return is translated into distance. The distance within which the echo is heard determined by the⦠turning the sound deflection upward prevents deposits accumulating on the sensor head, e.g. Figure 3.1: Working principle. After wave hits the target, the waves are reflected and the detector collects the signal. Based on the calculations made earlier, this provides a resolution of between 0.2 mm and 0.6 mm. Ultrasonic Sensor An Ultrasonic Sensor is a non-contact type device that can be used to measure distance as well as velocity of an object. It includes two modules like ultrasonic transmitter & receiver. This type of sensor can be manufactured in a smaller package than with separate elements, which is convenient for applications where size is at a premium.
