摘要
在日常生活中，浴室镜面的起雾问题给人们的使用带来诸多不便，传统的手动擦拭方式不仅耗时费力，且防雾效果短暂，难以满足便捷、舒适的生活需求。同时，浴室光照不足及缺乏休闲娱乐功能等问题，也影响着用户体验。
基于 STC89C52 单片机的浴室防雾镜系统，整合了 DHT11 温湿度检测模块、光照监测模块、人体感应传感器、触摸按键模块、加热片、照明灯、音乐播放模块等，实现了浴室镜面的自动防雾、智能照明及便捷的音乐控制功能。系统核心功能包括：通过 DHT11 检测镜面湿度，当湿度大于预设最大值时，控制加热片对镜面进行加热以去除雾气；借助光照监测模块和人体感应传感器，当监测到有人且光照强度过低时，自动打开照明灯；通过触摸按键可实现音乐的播放 / 停止、上一首 / 下一首切换，以及手动控制照明灯的开关。
该系统的实现，有效解决了浴室镜面起雾的问题，提升了浴室光照的智能化水平，增加了使用的便捷性和娱乐性，为用户提供了更舒适的浴室体验，同时也为同类智能家居设备的研发提供了参考，具有一定的实际应用价值。

ABSTRACT
In daily life, the fogging problem of bathroom mirrors brings many inconveniences to people’s use. The traditional manual wiping method is not only time-consuming and laborious, but also has a short anti-fog effect, which is difficult to meet the needs of a convenient and comfortable life. At the same time, problems such as insufficient bathroom lighting and lack of leisure and entertainment functions also affect the user experience.
The bathroom anti-fog mirror system based on STC89C52 single-chip microcomputer integrates DHT11 temperature and humidity detection module, light monitoring module, human body induction sensor, touch button module, heating sheet, lighting lamp, music player module, etc., realizing automatic anti-fog, intelligent lighting of bathroom mirror and convenient music control functions. The core functions of the system include: detecting the humidity of the mirror surface through DHT11, and when the humidity is greater than the preset maximum value, controlling the heating sheet to heat the mirror surface to remove fog; with the help of the light monitoring module and human body induction sensor, when it is detected that there is a person and the light intensity is too low, the lighting lamp is automatically turned on; through the touch button, you can start/stop music playback, previous song/next song, and manually control the switch of the lighting lamp.
The implementation of this system effectively solves the problem of fogging on bathroom mirrors, improves the intelligence level of bathroom lighting, increases the convenience and entertainment of use, provides users with a more comfortable bathroom experience, and also provides a reference for the research and development of similar smart home devices, with certain practical application value.
