基于单片机的高精度温度测量系统设计
Design of High-accuracy Temperature Detecting System Based on Single Chip Microcomputer
摘要
Abstract
A new high-accuracy temperature detecting system based on single-bus digital temperature sensor DS18820 and single chip microcomputer (SCM) is proposed. In this paper, the structure, characteristics and working principle of temperature sensor DS18820 is introduced. Hardware circuit and software programming (including temperature acquisition, temperature display and alarm control functions) of the temperature measurement system are designed based on DSl8820 and AT89S52 SCM. The whole system has a series of advantages of simple structure, high detection accuracy, long transmission distance, strong anti-interference ability, easy to read temperature and low cost. It has a bright application future in daily life and scientific research for temperature measurement.关键词
