摘要
为满足数据中心机房、档案室、图书馆、仓储库房、电力机柜等场所对环境温湿度监控的要求,设计一款基于ESP32微控制器和SHT20温湿度传感器的无线温湿度监控系统。该系统通过SHT20温湿度传感器采集环境温湿度,经ESP32微控制器进行数据处理,在OLED显示屏实时显示采集的温湿度值;当温湿度值超出报警阈值时系统可自动启动蜂鸣器报警。该系统同时搭载WIFI模块和RS485总线,通过Modbus数据协议实现温湿度的远程监控。
To meet the requirements of environmental temperature and humidity monitoring in data center rooms,archives,libraries,warehouses,power cabinets,and other places,a wireless temperature and humidity monitoring system based on ESP32 microcontroller and SHT20 temperature and humidity sensor is designed.The system collects environmental temperature and humidity through the SHT20 temperature and humidity sensor,processes the data through the ESP32 microcontroller,and displays the collected temperature and humidity values in real-time on the OLED display screen;When the temperature and humidity values exceed the alarm threshold,the system can automatically activate the buzzer alarm.The system is equipped with both WIFI module and RS485 bus,and remote monitoring of temperature and humidity is achieved through Modbus data protocol.
