Traditional home management mostly relies on manual operations, which has problems such as low security reliability, untimely environmental regulation, and energy waste, making it difficult to meet the needs of modern families for an efficient and intelligent life.The smart home system based on the STM32F103C8T6 microcontroller integrates AS608 fingerprint module, DHT11 temperature and humidity detection module, MQ-135 air quality detection module, 5516 light detection module, D203S human body pyroelectric induction module, 3 independent buttons, OLED display, ESP8266WiFi module and executive devices (door lock, air conditioner, humidifier, ventilation system, lamps, etc.), realizing automatic monitoring, intelligent regulation and safety management of the home environment. The core functions of the system include: controlling the door lock through the AS608 fingerprint module, opening the door when the fingerprint matches correctly, automatically closing after 5 seconds, and supporting adding or deleting fingerprints through buttons; detecting indoor temperature and humidity with DHT11, starting air conditioning heating when the temperature is below the minimum value, starting air conditioning cooling when it is above the maximum value, and starting the humidifier when the humidity is below the minimum value; using MQ-135 to detect air quality, and starting the ventilation system when it exceeds the standard; detecting light value through 5516, combined with D203S human body induction module, automatically turning on the light when there is a person and the light is below the minimum value; supporting setting various parameter thresholds and manually controlling each device through buttons; real-time display of various monitoring data and equipment status through the OLED display; sending data to the mobile phone through the ESP8266WiFi module, supporting the mobile phone to set thresholds and remotely control each device.The implementation of this system effectively improves the intelligence, safety and comfort of home life, reduces manual intervention, realizes the rational use of resources, provides an efficient and convenient smart home solution for modern families, and also provides a reference for the research and development of similar smart home equipment, with high practical application value.Keywords:STM32F103C8T6; Smart home system; Sensor; Intelligent regulation; WiFi communication; Fingerprint recognition目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 指纹识别模块选择2.1.3 温湿度检测模块选择2.1.4 空气质量检测模块选择2.1.5 光照检测模块选择2.1.6 人体感应模块选择2.1.7 按键模块选择2.1.8 显示模块选择2.1.9 WiFi 模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 指纹识别模块电路3.3 温湿度检测模块电路3.4 空气质量检测模块电路3.5 光照检测模块电路3.6 人体感应模块电路3.7 显示模块电路3.8 WiFi 模块电路3.9 按键模块电路3.10 执行设备驱动电路第4章 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 WiFi模块子流程设计4.6 温度检测模块子流程4.7 ADC模数转换子流程设计第 5 章 实物测试5.1 整体实物测试5.2 指纹识别模块功能测试5.3 温湿度检测模块功能测试5.4 空气质量检测模块功能测试5.5 光照检测与人体感应模块联合功能测试5.6 WiFi 模块功能测试5.7 按键设置与显示功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
