With the development of science and technology, the use of ultrasound to make precise measurements have become possible due to the ultrasonic distance measurement is a non-contact detection technology that can use a variety of environments, more hygienic than other instruments, and more resistant to moisture, dust, high temperature, corrosive gas and other harsh environments. The intelligent ultrasonic ranging system consists of ultrasonic distance measurement section, a display section, main section, voice chip (1) is mainly used ultrasonic ultrasonic ranging module, transmit the data back to the microcontroller processing. (2) display part by the lcd display (3) main part consists of 51 single-chip and its peripheral circuit. (4) voice sound chip main control chip microcontroller. The system design has been completed to achieve the following functions. 1) lcd instantly displays the current distance value. 2) The distance value can be accurate to centimeters. 3) play its measured dist
