Design and Debugging of Small Monitoring System of Temperature and Humidity

温湿度监测控制系统对室内温湿度进行调节,以满足人们对生活环境舒适度的要求。设计了一款温湿度监测系统,其主要通过数字型温湿度传感器DHT11对室内的温度湿度进行采集,将监测到的温湿度数据传输给STC89C52单片机,并与预先设置好的上下限阈值进行比较。如果测量值超过预设阈值,则蜂鸣器闪烁并报警提示,同时系统向外部设备发出调节指令,实现温湿度的监测与调控。该系统具有操作简单、成本低、调控安全可靠、精度较高的特点。

Regulating indoor temperature and humidity,the monitoring and control system of temperature and humidity is to meet people's needs for living environment comfort.The system mainly collects the indoor temperature and humidity by digital temperature and humidity sensor DHT11,and transmits the obtained temperature and humidity data to STC89C52 single chip microcomputer to compares with the preset upper and lower limit threshold values.If the measured value exceeds the preset threshold value,the buzzer flashes and gives an alarm.At the same time,the system sends adjustment instructions to external equipment to realize the monitoring and control of temperature and humidity.This system has such characteristics as easy operation,low cost,safe and reliable control and high precision.
