基于单片机温度监测报警装置的设计实现

The Design and Implementation of the Device Using the Temperature of the Single-Chip Microcomputer(SCM)to Monitor and Alarm

温度是工业生产的重要参数,也是人们日常生活中的非常关注的问题。本文主要介绍基于AT89C51的温度监测及报警系统。此系统利用单片机芯片烧录程序,利用LCD显示器显示温度,以便实时监视温度,当超过设定的温度上限时会通过蜂鸣器发出报警信号。

Temperature is an important parameter of industrial production and also of great con-cern in people’s daily life.This paper mainly talked about the monitoring and alarm system based on the temperature of AT89C5 1 .This system used the chip record program of the single- chip microcomputer （SCM）and the temperature on the LCD display so as to monitor the temperature in time,when it ex-ceeds the set limit the alarm signal will be sent through the buzzer.
