居家环境智能检测系统设计
摘要
随着城市化进程持续加快与居民生活品质不断提升，室内空气质量与居住环境安全已成为现代家庭关注的核心问题。装修材料释放的挥发性有机化合物、厨房燃气泄漏产生的可燃气体、室内活动引发的粉尘颗粒物积聚以及温湿度异常波动，均会直接影响居住者的呼吸健康与生理舒适度。传统居家环境检测多依赖单一功能便携仪器进行人工定期抽检，存在监测维度不足、无法实时跟踪环境参数变化、异常状态发现滞后等缺陷，难以实现居家环境质量的持续化、智能化动态管控。本文提出一种基于STM32F103C8T6单片机与蓝牙物联网技术的居家环境智能检测系统设计方案。系统集成空气质量监测、烟雾与可燃气检测、粉尘浓度采集、温湿度监测、本地人机交互、蓝牙无线数据上传、自定义报警阈值、手机端实时查看等核心功能。通过MQ-135空气质量传感器、MQ-2烟雾与可燃气传感器、GP2Y10粉尘传感器、DHT11温湿度传感器实时采集室内空气质量、烟雾及可燃气浓度、粉尘颗粒物浓度、环境温湿度等多维度数据，将采集参数与用户预设安全阈值自动比对；当空气质量、烟雾浓度、可燃气浓度、粉尘浓度超过设定最大值，或温湿度超出设定上下限区间时，设备即时触发本地声光报警，快速提示用户采取通风、净化和温湿度调节等措施。系统搭载独立按键，支持各项报警阈值自定义调节，搭配OLED显示屏实时本地展示全部监测数据与设备运行状态；同时通过蓝牙通信模块将实时监测数据同步上传至手机端，用户可通过手机APP随时随地查看居家环境参数，并远程修改各项报警阈值。本系统有效解决传统居家环境检测手段单一、监测不连续、异常预警不及时的痛点，实现室内空气质量与居住环境全天候自动监测、多参数异常实时报警、手机端远程可视化管理，大幅提升家庭居住环境智能化安全管控水平，具备良好的家居配套应用价值与推广前景。

Abstract
With the continuous acceleration of urbanization and the continuous improvement of residents’ quality of life, indoor air quality and living environment safety have become core concerns of modern families. Volatile organic compounds released from decoration materials, combustible gases generated from kitchen gas leakage, dust particle accumulation caused by indoor activities, and abnormal fluctuations in temperature and humidity will all directly affect the respiratory health and physiological comfort of residents. Traditional home environment detection mostly relies on single-function portable instruments for manual periodic sampling inspection, which has defects such as insufficient monitoring dimensions, inability to track environmental parameter changes in real time, and delayed detection of abnormal conditions. It is difficult to achieve continuous and intelligent dynamic management of home environment quality. This paper proposes a design scheme of home environment intelligent detection system based on STM32F103C8T6 microcontroller and Bluetooth IoT technology. The system integrates core functions such as air quality monitoring, smoke and combustible gas detection, dust concentration collection, temperature and humidity monitoring, local human-computer interaction, Bluetooth wireless data uploading, customizable alarm thresholds, and mobile phone real-time viewing. Through MQ-135 air quality sensor, MQ-2 smoke and combustible gas sensor, GP2Y10 dust sensor, and DHT11 temperature and humidity sensor, the system collects multi-dimensional data such as indoor air quality, smoke and combustible gas concentration, dust particle concentration, and environmental temperature and humidity in real time, and automatically compares the collected parameters with the safety thresholds preset by users. When the air quality, smoke concentration, combustible gas concentration, and dust concentration exceed the set maximum values, or the temperature and humidity exceed the set upper and lower limit ranges, the device immediately triggers local audible and visual alarms to quickly remind users to take measures such as ventilation, purification, and temperature and humidity regulation. Equipped with independent keys, the system supports custom adjustment of various alarm thresholds, and matches OLED display screen to locally display all monitoring data and equipment operation status in real time. Meanwhile, through the Bluetooth communication module, real-time monitoring data are synchronously uploaded to the mobile terminal. Users can view home environment parameters anytime and anywhere through the mobile APP, and remotely modify various alarm thresholds. This system effectively solves the pain points of single detection means, discontinuous monitoring, and untimely abnormal early warning in traditional home environment detection. It realizes all-weather automatic monitoring of indoor air quality and living environment, multi-parameter abnormal real-time alarming, and mobile phone remote visual management, greatly improving the intelligent safety management level of home living environment, and has excellent supporting application value and promotion prospects in the home appliance industry.
