基于STM32+ESP32+QT 上位机+云服务器平台设计的家庭温湿度监测系统
项目简介
本系统通过STM32采集温湿度数据，经ESP32无线传输至云端，结合QT上位机实现可视化监控，适用于智能家居、工业环境等场景，具备高精度、低功耗、易扩展的特点。
功能特点
实时监测：温湿度数据采集频率可调，支持本地OLED显示与云端同步；
远程访问：基于MQTT协议实现数据远程传输，支持上位机远程监测；
超限报警：蜂鸣器自动触发报警，温度阈值可自定义设置；
数据融合：双传感器（DHT11+NTC）结合算法优化，可降低测量误差。
硬件需求
模块 型号/规格
主控芯片 STM32F103C8T6
无线通信模块 ESP32-WROOM-32
温湿度传感器 DHT11
温度传感器 NTC热敏电阻（10kΩ@25℃）
显示模块 0.96寸OLED（I2C接口）
报警模块 5V有源蜂鸣器
辅助元件 4.7kΩ上拉电阻、0.1μF电容等
软件依赖
开发环境：Keil MDK（STM32）、ESP-IDF v5.3（ESP32）、Qt Creator 6.0（上位机）；
通信协议：MQTT（用于设备-云端交互）、UART（STM32与ESP32通信，与传感器通信）；
库文件：STM32标准库、ESP-IDF库、QT MQTT库。
使用说明
固件烧录：
STM32：通过Keil MDK编译固件，经USB转TTL模块烧录；
ESP32：使用ESP-IDF编译工程，通过串口下载至模块；
上位机配置：
在Qt Creator中自编译上位机程序，或使用已经编译的发行版。
在配置面板中配置MQTT服务器地址、订阅主题、端口号，连接设备即可接收数据。
连接成功后，点击环境监测面板即可对数据进行监测、分析、处理。
