摘 要
随着智能家居技术的发展，人们对居住环境的舒适度和智能化水平有了更高的要求。卫浴间作为家庭中重要的私密空间，其环境控制显得尤为重要。本设计旨在通过单片机技术实现卫浴间的智能化控制，以提升用户体验和环境质量。
本系统的核心控制单元采用的是STM32F103C8T6型号的单片机，它集成了多种功能模块，包括空气质量检测、一氧化碳（CO）浓度检测、温度检测、人体热释电传感器以及光照检测等。这些模块协同工作，使得系统能够实时监测卫浴空间内的空气质量状况、温度水平以及光照强度。通过对这些实时监测数据的分析，系统能够智能地自动控制相关设备，例如排气扇、窗户、照明灯以及加热模块的开启与关闭，以保持卫浴环境的舒适度。此外，系统还提供了用户交互界面，用户可以通过按键来设定各项环境参数的阈值，如空气质量、温度和光照强度的期望范围。为了方便用户随时了解当前卫浴间的环境状况，系统还配备了OLED显示屏，能够实时显示包括空气质量指数、温度读数、光照强度等在内的环境参数信息，确保用户能够直观地获取到所需的数据。
该智能卫浴间控制系统的设计，不仅能够根据环境变化自动调节卫浴间内的温度和光照，保持空气清新，还能通过节能控制减少能源消耗，提高能源利用效率。同时，系统的灵活性和实时数据显示功能，为用户提供了更加舒适便捷的卫浴体验。
ABSTRACT
With the development of smart home technology, people have higher requirements for the comfort and intelligence level of their living environment. As an important private space in the family, the control of the bathroom environment is particularly important. This design aims to achieve intelligent control of the bathroom through microcontroller technology, in order to improve user experience and environmental quality.
The core control unit of this system adopts the STM32F103C8T6 microcontroller, which integrates multiple functional modules, including air quality detection, carbon monoxide (CO) concentration detection, temperature detection, human pyroelectric sensor, and light detection. These modules work together to enable the system to monitor the air quality, temperature levels, and lighting intensity in the bathroom space in real time. By analyzing these real-time monitoring data, the system can intelligently and automatically control related equipment, such as exhaust fans, windows, lighting, and heating modules, to maintain the comfort of the bathroom environment. In addition, the system also provides a user interaction interface, where users can set thresholds for various environmental parameters such as air quality, temperature, and expected ranges of light intensity through buttons. In order to facilitate users to understand the current environmental conditions of the bathroom at any time, the system is also equipped with an OLED display screen, which can display real-time environmental parameter information including air quality index, temperature readings, light intensity, etc., ensuring that users can intuitively obtain the required data.
The design of this intelligent bathroom control system not only automatically adjusts the temperature and lighting in the bathroom according to environmental changes, keeping the air fresh, but also reduces energy consumption and improves energy utilization efficiency through energy-saving control. At the same time, the flexibility and real-time data display function of the system provide users with a more comfortable and convenient bathroom experience.
