基于单片机的语音智能加湿器控制系统设计

摘要

在日常生活中，适宜的室内湿度对人们的身体健康和生活舒适度至关重要。湿度偏低易导致皮肤干燥、呼吸道不适等问题，而传统加湿器存在操作繁琐、缺乏智能调控及安全提醒等不足。因此，研发一款集自动加湿、安全监测、智能交互于一体的语音智能加湿器控制系统具有重要的现实意义。

本设计提出了一种基于 STM32F103C8T6 单片机的语音智能加湿器控制系统。系统主要功能包括：通过 DHT11 温湿度传感器实时监测环境温湿度，当湿度低于设置最小值时自动开启加湿器，达到最大值后停止加湿；借助 YW01 水位检测模块监测水箱水位，缺水时立即停止加湿器工作并触发声光报警；利用 DS1302 时钟模块获取时间，支持设置定时闹钟，到时后进行 1 分钟声光提醒；通过按键可设置湿度上下限值、修正时间、设定闹钟，还能手动控制加湿器、MP3 音乐播放（DFPlayer Mini 模块）及小夜灯开关；所有监测数据通过 OLED 显示屏直观展示；通过 ECBO2 蓝牙模块实现远程功能，用户可在手机端查看温湿度和缺水状态，远程控制加湿器、音乐及小夜灯开关；同时支持 SU-03T 语音识别模块，通过语音指令控制加湿器的启停与模式切换、音乐及小夜灯开关。

该语音智能加湿器控制系统的作用在于，通过多模块协同工作实现了加湿过程的自动化、安全化与智能化。丰富的交互方式提升了操作便捷性，及时的报警功能保障了使用安全，为用户营造了舒适、健康的室内环境。

Design of Voice Intelligent Humidifier Control System Based on Single Chip Microcomputer

Abstract

In daily life, appropriate indoor humidity is crucial for people's physical health and living comfort. Low humidity can easily lead to dry skin, respiratory discomfort, and other problems, while traditional humidifiers have shortcomings such as cumbersome operation, lack of intelligent regulation, and safety reminders. Therefore, developing a voice intelligent humidifier control system that integrates automatic humidification, safety monitoring, and intelligent interaction has important practical significance.

This design proposes a voice intelligent humidifier control system based on STM32F103C8T6 microcontroller. The main functions of the system include: real-time monitoring of environmental temperature and humidity through the DHT11 temperature and humidity sensor, automatically turning on the humidifier when the humidity is below the set minimum value, and stopping humidification when the maximum value is reached; Use the YW01 water level detection module to monitor the water level in the water tank. When there is a shortage of water, immediately stop the humidifier from working and trigger an audible and visual alarm; Use DS1302 clock module to obtain time, support setting timed alarms, and provide a 1-minute sound and light reminder when the time is up; By pressing the buttons, you can set the upper and lower limits of humidity, adjust the time, set an alarm, and manually control the humidifier, MP3 music playback (DFPlayer Mini module), and night light switch; All monitoring data is visually displayed on an OLED screen; Remote functionality is achieved through the ECBO2 Bluetooth module, allowing users to view temperature, humidity, and water shortage status on their mobile phones, and remotely control humidifiers, music, and night light switches; Simultaneously supports SU-03T voice recognition module, which controls the start stop and mode switching of humidifier, music and night light switch through voice commands.

The function of this voice intelligent humidifier control system is to achieve automation, safety, and intelligence of the humidification process through the collaborative work of multiple modules. The rich interaction methods enhance the convenience of operation, and the timely alarm function ensures safe use, creating a comfortable and healthy indoor environment for users.
