摘要
随着人们生活品质的提升，对淋浴过程的舒适性与安全性要求日益提高。传统淋浴系统依赖手动调节水温，存在温度控制不精准、能源浪费、操作繁琐等问题，难以满足现代家庭对智能化卫浴体验的需求。
基于 STM32F103C8T6 单片机的智能淋浴系统（项目编号：mcuclub-dz-801），整合了防水式 DS18B20 水温检测模块、D203S 人体热释电传感器、OLED 显示屏、按键及加热控制装置，实现了淋浴水温的智能调节与状态监测功能。系统核心功能包括：通过 DS18B20 实时检测水温，精度可达 ±0.5℃，并在 OLED 显示屏同步显示；D203S 检测到浴室有人时，若水温低于预设最小值，自动启动加热装置，当水温升至预设最大值时，加热装置自动关闭；支持通过按键设置水温上下限阈值，也可手动控制加热开关，适应不同用户的温度偏好。
该系统的实现，有效提升了淋浴水温控制的精准性与便捷性，通过人感触发的自动加热机制减少了能源浪费，同时直观的显示与简单的操作提升了用户体验，为智能卫浴设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the improvement of people’s living standards, there is an increasing demand for comfort and safety during showering. Traditional shower systems rely on manual temperature adjustment, which has problems such as inaccurate temperature control, energy waste, and cumbersome operation, making it difficult to meet the needs of modern families for an intelligent bathroom experience.
The intelligent shower system based on the STM32F103C8T6 microcontroller (project number: mcuclub-dz-801) integrates a waterproof DS18B20 water temperature detection module, a D203S human body pyroelectric sensor, an OLED display, buttons, and a heating control device, realizing intelligent adjustment of shower water temperature and status monitoring functions. The core functions of the system include: real-time detection of water temperature through DS18B20 with an accuracy of ±0.5℃, which is synchronously displayed on the OLED screen; when the D203S detects someone in the bathroom, if the water temperature is lower than the preset minimum value, the heating device is automatically started, and when the water temperature rises to the preset maximum value, the heating device is automatically turned off; it supports setting the upper and lower temperature thresholds through buttons, and can also manually control the heating switch to adapt to the temperature preferences of different users.
The implementation of this system effectively improves the accuracy and convenience of shower water temperature control. The automatic heating mechanism triggered by human sensing reduces energy waste. At the same time, the intuitive display and simple operation enhance the user experience, providing a reference for the research and development of intelligent bathroom equipment, and having high practical application value.
