摘 要
水资源是人类社会生存和发展的重要基础，但随着全球人口的增加和气候变化的影响，水资源的合理管理和有效利用变得尤为重要。在日常生活中，水龙头是我们获取自来水的主要方式之一，因此，对水龙头的控制和管理变得至关重要。传统的水龙头存在水资源浪费和不便利的问题，例如长时间不关水龙头、水温不稳定等。因此，设计一种能够智能控制水流和水温的水龙头控制模块对于提高水资源利用效率和用户体验具有重要意义。此次设计一种温度可控式超声波感应水龙头控制模块的设计，该模块的核心控制器是STM32F103C8T6单片机。该模块具备多项功能，旨在实现智能化的水龙头控制，以提高水资源的有效利用。以下是该模块的主要功能概述：红外避障管检测： 通过红外避障管检测是否有人靠近水龙头。如果有人靠近，系统将触发水龙头出水，持续出水5秒，之后自动关闭，以满足用户的需求。水温控制： 模块集成了防水式DS18B20温度传感器，用于测量水温。用户可以设置一个出水温度，当水温低于设置的出水温度减一度时，系统将启动加热设备，以升高水温；当水温高于设置的出水温度加一度时，系统将启动制冷设备，以降低水温，确保出水温度在合适的范围内。环境温度测量： 同样使用DS18B20传感器测量环境温度，以便监测环境温度变化，可能影响水温控制。按键设置： 通过面板上的按键，用户可以设置出水时间和出水温度，以满足不同的需求和季节变化。OLED显示屏： 模块集成了OLED显示屏，用于实时显示测量数据，包括水温、环境温度、出水时间等，以便用户随时监控和调整设置。这一设计旨在实现水资源的智能管理和节约利用，同时提供了方便的用户界面和实时监测功能。通过综合利用传感器技术和单片机控制，该模块为温度可控式超声波感应水龙头控制提供了一种高效且智能的解决方案，为未来的智能水龙头系统的发展提供了有趣的示例。

Abstract
Water resources serve as a crucial foundation for human survival and development. However, with the increasing global population and the impact of climate change, the rational management and efficient utilization of water resources have become especially vital. In daily life, faucets are one of the primary means by which we access tap water. Therefore, controlling and managing faucets have become essential. Traditional faucets suffer from issues such as water wastage due to prolonged flow and inconsistent water temperature control.Hence, the design of a faucet control module capable of intelligent water flow and temperature control holds significant significance in enhancing water resource efficiency and user experience. This study presents the design of a temperature-controlled ultrasonic sensor-based faucet control module with the STM32F103C8T6 microcontroller as the core controller. The module encompasses several key functions:Infrared Obstacle Detection: Utilizing an infrared obstacle detection sensor, the module detects the presence of individuals near the faucet. If someone approaches, the system triggers the faucet to dispense water for 5 seconds before automatically shutting off, meeting the user’s requirements.Water Temperature Control: The module integrates a waterproof DS18B20 temperature sensor to measure water temperature. Users can set a desired output temperature. When the water temperature falls one degree below the set output temperature, the system activates a heating device to raise the water temperature. Conversely, if the water temperature exceeds the set output temperature by one degree, the system initiates a cooling device to lower the water temperature, ensuring that the water temperature remains within an appropriate range.Environmental Temperature Measurement: The DS18B20 sensor is also employed to measure the ambient temperature, enabling the monitoring of temperature variations that may affect water temperature control.Button Configuration: Through buttons on the module’s panel, users can configure the water flow duration and output temperature, adapting to different requirements and seasonal changes.OLED Display Screen: The module is equipped with an OLED display screen, providing real-time data visualization, including water temperature, environmental temperature, and water flow duration. This allows users to monitor and adjust settings conveniently.This design aims to realize intelligent water resource management and conservation while offering user-friendly interfaces and real-time monitoring capabilities. By effectively harnessing sensor technology and microcontroller control, this module provides an efficient and intelligent solution for temperature-controlled ultrasonic sensor-based faucet control, offering an intriguing example for the future development of intelligent faucet systems.
Keywords: Intelligent faucet, ultrasonic sensor, temperature control, water conservation management, environmentally friendly technology.
