摘 要
采用单片机对温度、湿度等环境参数进行监测是一个工业生产中经常遇到的监测
问题，采用单片机不仅具有监测方便、操作简单等优点，而且可以在节约成本的同时
大幅度的提高监测质量。本文设计了单片机构成的环境温度、湿度参数实时监测装置，
本装置以单片机 AT89C51 为控制核心，采用独特的单总线数字式温度传感器 DS18B20
进行温度采集，采用湿敏电容 HS1101 对湿度参数进行采集。LCD 液晶显示屏对于当
前的温度值和湿度值进行实时的显示，可以方便用户直观的了解所测得的温度、湿度
环境参数值。用户可使用按键根据自身要求设定温湿度上下限，同时，报警装置可依
据用户的设定针对温湿度超限情况进行报警。
关键词：温湿度监测；超限报警；LCD 显示
Abstract
MCU is always used in industry measurement as temperature and humidity
measurement. With MCU, it can be more convenient and simple to complete the
measurement e(ciently. The paper designs a real-time temperature and humidity
measurement device based on MCU. The device adopts AT89C52 as the control.
The
device also make use of DS18B20 to obtain the digital temperature signal and
HS1101 to
gain the analogue humidity signal. In the design, LCD is used to display the
consumers the
real-time temperature and humidity clearly. The consumer can use the buttons to
change
the upper and lower limits of the temperature and humidity. And the alert in the
design
should work based on the limits set up by the consumers.
Keywords：temperature and humidity measurement; alert over-limit;
