摘要
随着人们对生活舒适度要求的不断提高和对室内湿度管理重视程度的日益增强，智能、便捷的加湿器成为改善人居环境的重要设备。传统的加湿器功能单一，多依赖手动操作开关，无法根据环境湿度自动调节，且缺乏缺水保护机制，不仅使用不便，还存在安全隐患，难以满足现代生活对智能化湿度控制的需求。
基于 STC12C5A60S2 单片机的语音智能加湿器控制系统，整合了 DHT11 温湿度传感器、YW-01D 水位检测模块、LCD1602 显示屏、按键、蓝牙模块 ECB02 及语音识别模块 SU-03T 等硬件，实现了多项核心功能：通过 DHT11 检测环境温湿度，当湿度低于设置最小值时自动开启加湿器；借助 YW-01D 检测水位，缺水时停止加湿并触发声光报警；通过按键可设置湿度上下限，也能手动控制加湿器；LCD1602 实时显示温湿度及缺水状态；蓝牙模块支持远程查看数据和控制加湿器开关；语音识别模块可通过语音指令控制加湿器的开关及模式切换。
该系统的实现，有效提升了加湿器的智能化和自动化水平，实现了湿度的精准控制和安全保护，减少了人工干预，为家庭、办公等场景提供了便捷、可靠的湿度管理方案，同时也为智能家电与语音交互技术的融合应用提供了有益参考，具有一定的实际应用价值。

ABSTRACT
With the continuous improvement of people’s requirements for living comfort and the increasing emphasis on indoor humidity management, intelligent and convenient humidifiers have become important devices for improving living environments. Traditional humidifiers have single functions, mostly relying on manual operation to turn on and off, unable to automatically adjust according to environmental humidity, and lack a water shortage protection mechanism. They are not only inconvenient to use but also have potential safety hazards, making it difficult to meet the needs of modern life for intelligent humidity control.
The voice-controlled intelligent humidifier control system based on the STC12C5A60S2 single-chip microcomputer integrates hardware such as DHT11 temperature and humidity sensors, YW-01D water level detection modules, LCD1602 displays, buttons, Bluetooth module ECB02, and voice recognition module SU-03T, realizing several core functions: detecting environmental temperature and humidity through DHT11, and automatically turning on the humidifier when the humidity is lower than the set minimum value; detecting the water level with the help of YW-01D, stopping humidification and triggering an audible and visual alarm when there is a water shortage; setting the upper and lower humidity limits through buttons, and also manually controlling the humidifier; LCD1602 displaying temperature, humidity and water shortage status in real time; the Bluetooth module supports remote viewing of data and controlling the on/off of the humidifier; the voice recognition module can control the on/off and mode switching of the humidifier through voice commands.
The realization of this system effectively improves the intelligence and automation level of the humidifier, realizes precise humidity control and safety protection, reduces manual intervention, provides a convenient and reliable humidity management solution for home, office and other scenarios, and also provides a useful reference for the integration of smart home appliances and voice interaction technology, which has certain practical application value.
