摘要
在现代家居生活中，浴室环境的舒适与安全对提升居住体验具有重要意义。传统的浴室管理依赖人工操作，存在温湿度调节不及时、空气质量把控滞后等问题，难以满足智能化家居的需求。
基于 STM32F103C8T6 单片机的浴室环境监测系统，整合了 DS18B20 温度传感器、DHT11 湿度传感器、MQ-135 空气质量传感器、5516 光敏电阻、D203S 人体热释电传感器、DFPlayer Mini 音乐播放器、3 个独立按键、OLED 显示屏、ESP8266WiFi 模块及执行设备（加热装置、吹风装置、照明灯、通风设备），实现了浴室环境的自动化监测与智能调控。系统核心功能包括：通过 DS18B20 检测卫浴温度，开启洗浴模式时，温度不在设置范围内则自动加热（加热和吹风）或制冷（吹风）；通过 DHT11 检测湿度，湿度大于最大值时启动通风除湿；借助 MQ-135 检测空气质量，数值超限时进行通风换气；利用 5516 光敏电阻和 D203S 人体热释电传感器，有人且光照低于最小值时自动开灯；支持通过按键设置各阈值、手动控制器件；通过 OLED 显示屏显示测量数据；通过 ESP8266WiFi 模块实现手机端获取数据、设置阈值及远程控制。
该系统的实现，有效提升了浴室环境调控的自动化与智能化水平，减少了人工干预，保障了浴室环境的舒适与安全，为智能家居浴室场景提供了高效解决方案，同时为同类家居环境监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
In modern home life, the comfort and safety of the bathroom environment are of great significance for improving the living experience. Traditional bathroom management relies on manual operations, with problems such as untimely temperature and humidity regulation and delayed air quality control, which are difficult to meet the needs of intelligent homes.
The bathroom environment monitoring system based on the STM32F103C8T6 microcontroller integrates DS18B20 temperature sensor, DHT11 humidity sensor, MQ-135 air quality sensor, 5516 photoresistor, D203S human pyroelectric sensor, DFPlayer Mini music player, 3 independent buttons, OLED display, ESP8266WiFi module, and executive devices (heating device, blowing device, lighting lamp, ventilation equipment), realizing automatic monitoring and intelligent regulation of the bathroom environment. The core functions of the system include: detecting bathroom temperature through DS18B20; when the bathing mode is turned on, if the temperature is not within the set range, it will automatically heat (heating and blowing) or cool (blowing); detecting humidity through DHT11, and starting ventilation and dehumidification when the humidity is greater than the maximum value; detecting air quality with MQ-135, and performing ventilation when the value exceeds the limit; using 5516 photoresistor and D203S human pyroelectric sensor to automatically turn on the lighting when there is a person and the light is lower than the minimum value; supporting setting various thresholds and manually controlling devices through buttons; displaying measurement data through OLED display; realizing mobile phone data acquisition, threshold setting and remote control through ESP8266WiFi module.
The implementation of this system effectively improves the automation and intelligence level of bathroom environment regulation, reduces manual intervention, ensures the comfort and safety of the bathroom environment, provides an efficient solution for the smart home bathroom scenario, and also offers a reference for the research and development of similar home environment monitoring equipment, with high practical application value.
