摘要
随着人们生活品质的不断提升，室内环境的舒适调控对保障人体健康、提高生活质量具有重要意义。传统的加湿器手动控制方式不仅依赖人工判断、操作繁琐，还存在湿度调节不精准、易造成资源浪费等问题，难以满足智能化家居生活的需求。
基于 STM32F103C8T6 单片机的智能加湿器控制系统，整合了 DHT11 温湿度传感器、按键、OLED 显示屏、ECB02 蓝牙模块及执行设备（加湿器），实现了室内湿度的自动化监测与智能调控。系统核心功能包括：通过 DHT11 实时监测温湿度，当检测到温度小于最小值时自动关闭加湿器；当湿度小于最小值时自动控制加湿器打开，湿度大于最大值时关闭加湿器；支持通过按键设置温湿度的阈值以及控制加湿器的开关；通过 OLED 显示屏实时显示当前检测的温湿度和加湿器的开关状态；利用蓝牙模块将检测的数据传输到手机端，手机端可设置温湿度和控制加湿器的开关。
该系统的实现，有效提升了加湿器控制的自动化与智能化水平，减少了人工操作，确保了室内湿度的适宜与稳定，为智能化家居生活提供了高效、便捷的解决方案，同时为同类家居环境调控设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous improvement of people's living standards, the comfortable regulation of indoor environments is of great significance for ensuring human health and enhancing the quality of life. The traditional manual control method of humidifiers not only relies on manual judgment and is cumbersome to operate, but also has problems such as inaccurate humidity adjustment and easy resource waste, which is difficult to meet the needs of intelligent home life.
The intelligent humidifier control system based on the STM32F103C8T6 microcontroller integrates the DHT11 temperature and humidity sensor, buttons, OLED display, ECB02 Bluetooth module and executive equipment (humidifier), realizing the automatic monitoring and intelligent regulation of indoor humidity. The core functions of the system include: real-time monitoring of temperature and humidity through DHT11, automatically turning off the humidifier when the detected temperature is lower than the minimum value; automatically controlling the humidifier to turn on when the humidity is lower than the minimum value, and turning off the humidifier when the humidity is higher than the maximum value; supporting the setting of temperature and humidity thresholds and controlling the on/off of the humidifier through buttons; real-time display of the currently detected temperature and humidity and the on/off status of the humidifier through the OLED display; transmitting the detected data to the mobile phone terminal through the Bluetooth module, and the mobile phone terminal can set the temperature and humidity and control the on/off of the humidifier.
The implementation of this system effectively improves the automation and intelligence level of humidifier control, reduces manual operations, ensures the appropriateness and stability of indoor humidity, provides an efficient and convenient solution for intelligent home life, and also offers a reference for the research and development of similar home environment regulation equipment, with high practical application value.
