基于单片机的家庭温湿度和防漏水系统设计
摘 要
在现代社会，家庭安全和舒适性一直备受重视。温湿度和水位是关键的环境参数，它们对于维持家庭内部的舒适性和安全性至关重要。因此，设计一种基于单片机的家庭温湿度和防漏水系统具有重要的研究背景和意义。
本论文基于STM32F103C8T6单片机，设计了一种家庭温湿度和防漏水系统，以满足家庭环境监测和安全性的需求。该系统具体功能如下：温湿度监测：系统通过DHT11传感器测量环境的温度和湿度。当温湿度不在预设范围内时，系统会触发声光报警，提醒用户可能的环境问题。水位检测：系统集成水位检测模块，用于监测液体容器的水位。如果水位高于设置的最小值，系统将发出声光警报，以指示潜在的漏水风险。设置阈值：系统具备按键设置功能，允许用户自定义温湿度和水位的阈值，以满足特定需求和环境。OLED显示：系统配备了OLED显示屏，用于实时显示温湿度和水位的测量数值，提供用户友好的界面。声光报警控制：系统整合了语音识别模块，用户可以通过语音命令打开或关闭声光报警，增加了操作的便捷性。
该系统能够实时监测家庭环境的温湿度和水位情况，同时提供了多种方式的警报和用户交互，以增强家庭安全性和便捷性。这一设计为家庭温湿度监测和防漏水提供了有效的解决方案，有望在家庭环境中得到广泛应用。

Abstract
In modern society, home safety and comfort have always been of great concern. Temperature, humidity, and water level are crucial environmental parameters, and they are essential for maintaining the comfort and safety of a household. Therefore, the design of a home temperature, humidity, and leak prevention system based on a microcontroller is of significant research background and importance.
This paper is based on the STM32F103C8T6 microcontroller and presents a home temperature, humidity, and leak prevention system to meet the needs of environmental monitoring and safety in households. The specific functions of this system are as follows:
Temperature and Humidity Monitoring: The system utilizes the DHT11 sensor to measure the temperature and humidity in the environment. When the temperature and humidity fall outside the preset range, the system triggers audio and visual alarms to alert users to potential environmental issues.Water Level Detection: The system integrates a water level detection module for monitoring the water level in liquid containers. If the water level exceeds the set minimum value, the system emits audio and visual alarms to indicate potential water leakage risks.Threshold Configuration: The system incorporates keypad-based threshold setting functionality, allowing users to customize temperature, humidity, and water level thresholds to meet specific requirements and environmental conditions.OLED Display: An OLED display screen is included in the system to provide real-time readings of temperature, humidity, and water level, offering a user-friendly interface.Audio and Visual Alarm Control: The system is equipped with a voice recognition module, enabling users to open or close audio and visual alarms through voice commands, enhancing operational convenience.
This system can continuously monitor the temperature, humidity, and water levels in a household environment. It offers multiple ways to alert users and interact with them, ultimately enhancing home safety and convenience. This design provides an effective solution for home temperature and humidity monitoring and leak prevention, with the potential for wide-ranging applications in household environments.
