随着物联网技术(Internet of Things,IoT)和云计算等技术的发展,智能家居系统正在逐步兴起.环境监测可以说是智能家居系统不可或缺的一部分,为方便用户实时监测室内的环境质量,实现在线环境监测从而达成远程监测与控制,设计了一种基于物联网技术的室内环境监测系统.该系统以ESP32-WROOM-32作为系统的中央处理器,以DHT11温湿度传感器、DS18B20温度传感器、GY-302 BH1750光强传感器模块、MQ-135气体传感器、MQ-6气体传感器等构成该系统数据收集节点,并将采集的环境参数的数据信号传递给ESP32,ESP32将数据上传到云服务器.并使用App Inventor完成上位机软件的设计,连接云服务器,最终在手机App端呈现数据.用户可以通过手机端实时查看室内的环境状态信息,并且可以通过手机App来控制室内台灯的开关.
The Indoor Environment Monitoring System Based on the Internet of Things
With the development of technologies such as the Internet of Things(IoT)and cloud computing,the smart home system is gradually emerging,and environmental monitoring is arguably an integral part in this process.In order to facilitate users to monitor indoor environmental quality in real time and realize online environmental monitoring to achieve remote monitoring and control,this paper designs an indoor environment monitoring system based on the Internet of Things.The system uses ESP32-WROOM-32 as its central processor,uses the DHT 11 temperature and humidity sensor,the DS18B20 temperature sensor,the GY-302 BH1750 light intensity sensor module,the MQ-135 gas sensor and the MQ-6 gas sensor to constitute its data collection node,and transmits the collected data signal of environmental parameters to ESP32 which uploads the data to the cloud server.And,it uses App Inventor to complete the design of upper computer software,connects it to the cloud server,and finally pres-ents the data on the mobile App.Users can view indoor environment status information in real time through the mobile side,and control the switch of the indoor desk lamp through the mobile App.
