摘要
随着城市化进程的加快和环境问题的日益凸显，空气质量监测对公众健康和环境管理的重要性愈发显著。传统的空气质量监测方式多依赖固定监测站，存在覆盖范围有限、数据更新滞后、难以满足个人或特定区域实时监测需求等问题，且普通用户难以便捷获取详细的空气质量数据。
基于 STM32F103C8T6 单片机的远程空气质量监测系统，整合了 GP2Y10 PM2.5 传感器、MS1100 甲醛传感器、MQ-7 一氧化碳传感器及 ESP8266 WiFi 模块，实现了环境中多种污染物的实时监测与远程数据传输。系统核心功能包括：通过 GP2Y10 检测 PM2.5 浓度，MS1100 监测甲醛含量，MQ-7 检测一氧化碳浓度；借助 ESP8266 WiFi 模块将各项监测数据实时传输至手机端，使用户能远程查看 PM2.5、甲醛、一氧化碳的实时浓度。
该系统的实现，有效突破了传统空气质量监测的时空限制，提升了监测的实时性与便捷性，为用户提供了精准的空气质量数据，助力公众健康防护与环境管理，同时为同类远程监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the acceleration of urbanization and the increasing prominence of environmental issues, air quality monitoring has become increasingly significant for public health and environmental management. Traditional air quality monitoring methods mostly rely on fixed monitoring stations, which have problems such as limited coverage, delayed data updates, difficulty in meeting the real-time monitoring needs of individuals or specific areas, and it is also difficult for ordinary users to conveniently obtain detailed air quality data.
The remote air quality monitoring system based on the STM32F103C8T6 microcontroller integrates GP2Y10 PM2.5 sensor, MS1100 formaldehyde sensor, MQ-7 carbon monoxide sensor and ESP8266 WiFi module, realizing real-time monitoring of various pollutants in the environment and remote data transmission. The core functions of the system include: detecting PM2.5 concentration through GP2Y10, monitoring formaldehyde content through MS1100, and detecting carbon monoxide concentration through MQ-7; transmitting all monitoring data to the mobile phone in real time with the help of the ESP8266 WiFi module, enabling users to remotely view the real-time concentrations of PM2.5, formaldehyde and carbon monoxide.
The implementation of this system effectively breaks through the temporal and spatial limitations of traditional air quality monitoring, improves the real-time performance and convenience of monitoring, provides users with accurate air quality data, helps public health protection and environmental management, and also provides a reference for the research and development of similar remote monitoring equipment, with high practical application value.
