摘要
为了远程实时监测温室大棚农作物生长环境参数,利用物联网技术,采用WiFi技术、DHT11数字温湿度传感器、光照传感器BH1750FVI和土壤湿度传感器,以Arduino Uno微处理器和Web服务器为平台设计出远程温室大棚实时监测系统。通过试验,系统可实时给出监测数据,测量结果随着环境参数的改变而改变。当测量数据超过设定的阈值时,自动开启或关闭控制开关,对温湿度、光照和土壤湿度进行智能调节。结果表明,采用提出的方法,简单的电路可完成复杂的功能,大大降低了设计成本。
In order to realize remote real-time monitoring of growing environment parameters of greenhouse crops,a remote real-time monitoring system for greenhouses was designed with the help of IOT technology by use of WiFi technology,DHT11 digital temperature/humidity sensor,light sensor BH1750FVI and soil humidity sensor,on a platform composed of the Arduino Uno microprocessor and Web server.Tests verified that the proposed system could give real-time monitoring data.Measurement results changed while environmental parameters altered.When measurement data exceeded the set threshold,the control switch would be turned on or off automatically to implement intelligent regulation of temperature/humidity,illumination and soil humidity.It was concluded that by adopting the approach proposed,a simple circuit could accomplish complex functions and the design cost could be reduced to a great extent.
