实验室智能温湿度监控系统设计

Design of Intelligent Temperature and Humidity Monitoring System in Laboratory

本设计根据实验室的环境特点,利用单片机结合传感器技术开发一套能实时监测实验室环境并及时报警的温湿度监测仪,DHT11数字温湿度传感器,AT89S51单片机为控制核心与其他电子外设结合而设计的该温湿度监测系统具有灵敏度高,响应速度快,抗干扰能力强,维护方便,安装方便等优点。监控系统可以通过按键设定报警温度和湿度的上限和下限。当警报激活时,相应的指示灯亮起,蜂鸣器报警。

According to the environmental characteristics of the laboratory,this design uses SCM combined with sensor technology to develop a set of temperature and humidity monitoring instrument which can real-time monitor the laboratory environment and timely alarm,DHT11 digital temperature and humidity sensor,AT89S51 microcontroller as the control core and other electronic peripherals.The temperature and humidity monitoring system has high sensitivity,fast response speed and anti-interference ability Strong,easy to maintain,easy to install and so on.The monitoring system can set the upper and lower limits of alarm temperature and humidity by pressing the key.When the alarm is activated,the corresponding indicator lights up and the buzzer gives an alarm.
