The system is capable of real-time monitoring of temperature, humidity, smoke concentration, formaldehyde concentration, and dust concentration within the vehicle. For temperature and humidity monitoring, the DHT11 sensor is employed. Should the temperature exceed the predefined normal range, the system will automatically activate the air conditioning unit (simulated by a fan). If the temperature remains within the normal range, continuous monitoring of temperature and humidity parameters will persist. The MQ-2 sensor is utilized for smoke concentration monitoring. Upon detecting abnormal smoke levels, the system will immediately initiate ventilation via the fan and trigger both audio and visual alarms. Normal smoke concentrations result in continued parameter monitoring. Formaldehyde concentration is monitored using the MS1100 sensor. Exceeding standard formaldehyde levels prompts automatic activation of the ventilation fan. Normal concentrations lead to ongoing monitoring. The GP2Y1014AU sensor monitors dust concentration. High dust levels trigger the negative ion generator for air purification. Normal dust concentrations maintain the monitoring state. An OLED display module provides real-time visualization of monitoring data, while a button module enables users to set threshold values for various parameters. Through the WiFi module, the system transmits monitoring data to mobile terminals in real time, thereby enabling remote monitoring and parameter adjustment.Key WordsVehicle;STM32 ;Sensor ; WiFi; Environment Monitoring目 录摘 要Abstract1 引 言1.1 选题背景及意义1.2 国内外发展历程1.2.1 国内研究现状1.2.2 国外研究现状2 系统总体设计2.1 整体设计方案2.2 主要元器件选择2.2.1 主控芯片选型2.2.2 温湿度检测模块选型2.2.3 烟雾检测模块选型2.2.4 甲醛检测模块选型2.2.5 粉尘检测模块选型3 硬件设计3.1 主控电路设计3.2 温湿度检测模块电路设计3.3 烟雾检测模块电路设计3.4 甲醛检测模块电路设计3.5 粉尘检测模块电路设计3.6 执行模块电路设计3.7 显示模块电路设计3.8 按键模块电路设计3.9 声光报警模块电路设计3.10 WiFi模块电路设计4 系统程序设计4.1 开发环境介绍4.2 主程序流程图设计4.3 温湿度检测模块子流程设计4.4 烟雾检测模块子流程设计4.5 甲醛检测模块子流程设计4.6 粉尘检测模块子流程设计4.7 WiFi模块子流程设计4.8 按键模块子流程设计5 系统调试5.1 温湿度检测模块实物测试5.2 烟雾检测模块实物测试5.3 甲醛检测模块实物测试5.4 粉尘检测模块实物测试5.5 WiFi模块实物测试5.6 测试结果6 结 论参考文献附录A 原理图附录B PCB附录C 主程序致 谢
