摘要
针对温室大棚在农业领域越来越得到广泛推广,数字化采集环境因素需求越来越得到重视,设计了基于ZigBee组网控制的温室大棚环境监控系统。系统主要由温湿度采集电路、光强传感器电路、ZigBee无线传输电路、电源管理电路、GSM数据传输电路等组成。通过SHT20温湿度采集传感器以及BH1750光强传感器采集环境因素,将各节点的环境因素通过ZigBee无线传感网络汇总处理,并永久保存至云端服务器,用户通过智能手机终端可以实时监测各项数据。测试结果表明,系统实现了对大棚内环境参数的采集、处理、传输、保存功能,具有低功耗、操作简便、体积小等特点,对用户在日常大棚中环境因素的采集起到方便管理以及便于维护的功能。
In the view of the digital collection of environmental factors demand for the greenhouses in the agricultural sector, the greenhouses environment monitoring system based on ZigBee network is designed. System consists of temperature and humidity acquisition circuit, the light intensity sen-sor circuit, ZigBee wireless transmission circuits, power management circuits and GSM data trans- mission circuit. By SHT20 temperature and humidity sensor acquisition and BH1750 light intensity sensor to gather environmental factors, the environmental factors of each node through ZigBee wireless sensor network, aggregated, and permanently saved to the cloud server. Users can use the App to monitor the data. Test results show that the system has advantages of the environmental parameters greenhouses collection, processing, transmission, storage function, low power consumption, easy operation, small size and other characteristics.
