基于NB-IoT的空气质量监测系统设计

Design of air quality monitoring system based on NB-IoT

文章结合嵌入式开发技术、物联网通信技术、云处理技术,设计了一款基于NB-IoT的空气质量监测系统。该系统采用STM32单片机采集空气质量参数,通过NB-IoT无线通信模块将空气质量参数传送至云服务器,云服务器完成数据解析和存储,可实时监测PM_(2.5)、CO、O_(3)、SO_(2)、NO_(2)5种空气质量参数。文章设计的空气质量监测系统采用模块化设计,更易于维护。

In this paper,an air quality monitoring system based on NB-IoT is designed by combining embedded development technology,Internet of Things communication technology and cloud processing technology.The system uses STM32 MCU to collect air quality parameters,and transmits air quality parameters to the cloud server through NB-IoT wireless communication module.The cloud server completes data analysis and storage,and can monitor PM_(2.5),CO,O_(3),SO_(2)and NO_(2)air quality parameters in real time.The air quality monitoring system designed in this paper adopts modular design and is easier to maintain.
