基于ESP32的温室大棚环境远程监控系统设计

Design of remote monitoring and control system for agricultural greenhouse environment based on ESP32

为提高设施农业环境监测水平,设计一种基于ESP32模块的温室大棚环境远程监控系统。系统主要包括环境信息采集模块、ESP32模块、输出控制模块和智能手机监控终端等。基于Android平台采用Blinker物联网解决方案设计了监控终端APP。系统能够采集温室大棚环境温湿度、光照强度、PM2.5浓度、CO_(2)浓度和门禁等信息,并通过WiFi网络将信息发送给手机终端,管理人员通过手机APP可查看温室大棚环境信息,也可对有关设备进行远程控制。制作样机并进行系统测试,结果表明,系统数据采集上传成功率最低为97.3%,平均网络丢包率为2.17%。系统运行稳定,具有成本低、实时性好、通信安全性高、工作可靠及操作简单等特点。

In order to improve the monitoring level of facility agricultural environment,a remote wireless monitoring system for agricultural greenhouse environment based on ESP32 module was designed.The system comprised of environmental information acquisition module,ESP32 control module,output module,and smartphone control terminal.The monitoring terminal APP was designed with blinker Internet of Things solution based on Android platform.Greenhouse environment temperature,humidity,light intensity,PM2.5 concentration,CO_(2)concentration,access control and other environmental information was collected through sensors and sent to the remote monitoring mobile phone via WiFi network.The environmental information of the greenhouse was viewed and the relevant greenhouse equipment was controlled remotely using a mobile APP.The system physical prototype was manufactured and an experiment was carried out.The results showed that the lowest success rate of data transmission of the terminal was 97.3%and the average networks packet loss rate was 2.17%.The system has many advantages such as stable operation low cost,good real-time,high communication security,high reliability and easy operation.
