Research of an Ultrasonic Telemeter Based on AT89C2051

摘要

This paper describes the principle and techniques of ultrasonic telemeter based on AT89C2051. The performance characteristics of the ultrasonic telemeter are studied theoretically and experimentally. The primary objective of the study was to determine the hardware principle circuit and the main software design, the computed simulation by Pspice is provided for the key part of the hardware circuit. In this paper it is demonstrated that this type of the ultrasonic telemeter is available.
