ABSTRACT
Ultrasonic frequently used in the measurement of distance, such as range finders and location of objects measuring instrument can all be achieved by ultrasound with its strong directivity, energy consumption slow and far away transmission distance. Ultrasonic Ranging will be used in a distance measurement system for backing a car, construction sites and industrial scene. For example: level, depth, length of pipeline and other occasions. Ultrasonic testing is often more rapid, convenient, simple, easy to do the real-time control. And the measurement accuracy can achieve practical industrial requirements in the development of measurement and control system has been widely applied. This paper introduces a low-cost, high-precision ultrasonic telemeter’s hardware and software design method. The ultrasonic telemeter can measure the distance form 0.10 M to 1.00M. Measurement accuracy is 1cm. It can display the measurement results on the LED Clearly.
