摘 要
随着生活水平的提高，人们对家居环境的安全与舒适性要求越来越高。传统的家居设备多为手动控制，无法实时监测环境变化并自动做出调整，存在诸多不便。因此，设计一款能够实时监测家居环境并自动预警的系统显得尤为重要。
本系统以STM32F103C8T6单片机为核心，硬件方面采用AD软件进行电路设计，集成人体热释电感应模块D203S、温度传感器DS18B20、光敏电阻、湿度传感器DHT11以及WIFI模块等组件。软件基于Keil 5开发，实现多种功能：通过人体感应模块自动控制照明灯开关；根据温度传感器数据智能调节风扇和窗帘状态；监测湿度和电源线温度，异常时进行声光报警并推送信息至手机APP；并通过按键用于阈值设置和手动设备控制，显示屏实时显示监测数据。
经过测试，系统运行稳定，各传感器数据采集准确，自动控制功能响应迅速，远程控制功能稳定，能够有效提升家居环境的安全性和舒适性，为智能家居生活提供了有力支持。

Abstract
With the improvement of living standards, people have increasingly high requirements for the safety and comfort of their home environment. Traditional home devices are mostly manually controlled, which cannot monitor environmental changes in real time and make automatic adjustments, resulting in many inconveniences. Therefore, it is particularly important to design a system that can monitor the home environment in real time and automatically issue warnings.
This system is based on the STM32F103C8T6 microcontroller, and the hardware is designed using AD software for circuit design. It integrates components such as the D203S human pyroelectric induction module, DS18B20 temperature sensor, photoresistor, DHT11 humidity sensor, and WIFI module. The software is developed based on Keil 5 and achieves multiple functions: automatic control of lighting switches through human body sensing modules; Intelligent adjustment of fan and curtain status based on temperature sensor data; Monitor humidity and power cord temperature, sound and light alarms in case of abnormalities, and push information to the mobile app; And it is used for threshold setting and manual device control through buttons, and the display screen displays monitoring data in real time.
After testing, the system runs stably, the data collection of each sensor is accurate, the automatic control function responds quickly, and the remote control function is stable. It can effectively improve the safety and comfort of the home environment, providing strong support for smart home life.
