摘　　要：采集温度数据是温度管理系统的首要任务。LM75以其优越的性能特点,可广泛用于各种温度管理系统。设计了基于51单片机的测温系统,该系统由温度传感器LM75采集温度数据,由51单片机读取其温度数据并显示。重点对LM75数据读写时序进行分析、研究,并给出了读取温度数据的程序流程图。其源程序在所设计的测温系统中成功运行,可迅速测得环境温度。Temperature data acquisition is the primary task of temperature management systems. With the superior performance, LM75 can be widely used in all kinds of temperature management systems. In this paper, a temperature measuring system based on MCS-51 is designed, in which LM75 is used to acquire temperature data, and MCS-51 is used to read and display the acquired temperature data. Data reading and writing sequences of LM75 is mainly analyzed and studied, and program flow chart for reading temperature data is given. The source program in the temperature measuring system is run successfully, and the environment temperature can be measured and displayed in short time
