基于单片机温湿度监控系统的设计

Design of Automatic Temperature and Humidity Monitoring System

设计了一个实时温湿度监控系统,通过USB转串口连接上位机与下位机,利用HS1100/HS1101湿度传感器采集环境湿度,利用数字温度传感器DS18B20采集环境温度,由单片机8051处理采集到的数据,控制1602LCD显示出实时温湿度。当温度超到系统设置的报警值时蜂鸣器报警,单片机同时能将采集的温湿度通过USB串口实时传给上位机。

This paper introduces the design of an real-time temperature and humidity monitoring system, which uses a humidity sensor HS1100/HS1101 to collecte humidity data, and applies a digital temperature sensor DS18B20 to acquire temperature data. The PC and the lower machine are connected by USB serial port, the SCM AT89C52 processes the collected data and shows the temperature and humidity on LCD real-timely. When the temperature achieved the set value, the buzzer will go of. The SCM AT89C52 can also transmit the collected data to PC through the USB port in real time.
