摘要
设计基于MSP430F149单片机为主控制单元,CC2530为数据采集单元的温室大棚数据采集系统。CC2530连接温湿度传感器AM2301、二氧化碳传感器TGS4161和光照传感器BH1750,对温室大棚内的温湿度、二氧化碳浓度和光照强度进行采集,并将采集到的数据发送给配有CC2530模块的MSP430F149单片机,由单片机对收到的数据进行分析处理并发给上位机存储显示。给出了系统的整体框图、采集电路和系统软件流程图。实际测试表明,系统能够准确的完成温湿度、二氧化碳浓度和光照强度的采集,功耗较低,具有智能化传感器网络的特点,在智能农业领域有着很好的市场前景和推广价值。
Greenhouse data acquisition system is designed by using MSP430F149 microcontroller as control unit and CC2530 as acquisition unit.The CC2530 connects temperature and humidity sensor AM2301,carbon dioxide sensor TGS4161 and light sensor BH1750,collects the temperature and humidity,carbon dioxide concentration and light intensity inside the greenhouse,and then sends the collected data to the MSP430F149 microcontroller with CC2530 module.The microcontroller analyzes and processes the data received and then sends the data to the host computer to store and display.The overall system block diagram,acquisition circuit and system software flowchart are showed in this paper.Actual tests show that the system is able to collect temperature and humidity,carbon dioxide concentration and light intensity accurately.It has low power consumption and the features of intelligent sensor networks.It has good market prospects and promotion value in the field of intelligent agriculture.
