If problems such as imbalanced indoor temperature and humidity, excessive formaldehyde, and high concentrations of CO ₂ and TVOC are not detected and intervened in a timely manner, they may cause respiratory discomfort, allergies, and other health hazards, especially affecting sensitive populations such as the elderly and children. Therefore, developing a device that can comprehensively and conveniently monitor indoor air quality is of great practical significance.This design proposes a household air quality detection system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting environmental temperature and humidity through DHT11 sensors, and automatically starting ventilation equipment when the temperature and humidity exceed the standard; Monitor formaldehyde concentration with MS1100 sensor, and synchronously turn on ventilation and purification equipment when exceeding the standard; Collect CO ₂ and TVOC data through SGP30 sensor, and trigger ventilation and purification linkage when exceeding the standard; Users can set various parameter thresholds and device switch states through buttons; OLED display screen displays real-time temperature and humidity, formaldehyde, CO ₂, and TVOC measurement values; Implementing data upload to mobile devices through ESP8266 WiFi module, supporting remote parameter settings and device control.The function of this system is to provide comprehensive air quality monitoring and intelligent control solutions for households. By real-time monitoring, automatic intervention, and remote control, we help users improve indoor environmental quality in a timely manner, reduce the impact of air pollution on health, and provide reliable guarantees for healthy living at home.Keywordsmicrocontroller; Household air quality testing; Sensors; Intelligent regulation; Remote Monitoring目 录1 绪论1.1 研究背景及意义1.2 国内外研究现状1.3 主要内容2 系统总体方案设计2.1系统总体设计2.2 主要模块方案选择3系统硬件设计3.1 总体硬件框架3.2 主控模块电路设计3.3 温湿度检测模块电路设计3.4 甲醛检测模块电路设计3.5 多气体检测模块电路设计3.6 显示模块电路设计3.7 按键模块电路设计3.8 执行控制模块电路设计3.9 通信模块电路设计4 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 OLED显示流程设计4.5 温湿度检测模块子流程4.6 SGP30模块子流程设计4.7 WiFi模块子流程设计5实物制作与功能测试5.1 实物制作5.2 环境参数采集与显示功能测试5.3 自动控制功能测试5.4 手动交互与阈值设置功能测试5.5 无线数据传输与远程控制功能测试6 总结参考文献致谢附录A 原理图附录B PCB附录C 主程序
