基于SimpliciTI的大棚温湿度无线监测系统设计

Design of greenhouse temperature and humidity wireless monitoring system based on Simplici TI

针对目前温室大棚温湿度监测大多采用人工监测或有线监测方式,设计了一种基于Simplici TI的大棚温湿度无线监测系统。该系统以遵循Simplici TI协议的CC2500无线收发器组成星型无线传感器网络,传感器节点采用HTU21D数字温湿度传感器测量各节点温湿度值,由OLED12832模块现场显示,中央节点把收到的数据经串口上传PC机,并用由VC++6.0制作的监视软件进行显示和记录。测试表明,该系统具有成本低、组网灵活、测量精度高和实用性强等优点。

Aiming at the greenhouse temperature and humidity monitoring mostly adopts manual monitoring or wired monitoring mode, designed a temperature and humidity wireless monitoring system based on SimpliciTL The system has made use of CC2500 wireless transceiver which follows SimpliciTI protocol to form a star wireless sensor network, the sensor nodes use the digital temperature and humidity sensor of HTU21D to measure the temperature and humidity values of each node, displays by OLED12832 site, the central node transfers the received data to PC through the serial port, And uses the monitoring software made by VC＋＋6.0 to display and record. The test shows that, this system has the advantages of low cost, flexible networking, high measuring precision and strong practicability etc.
