中文摘要：

二氧化碳气肥增施控制系统采用Arduino Mega 2560作为主控制器,采用AM2301、CM1101、BH1750实现温室内温湿度、二氧化碳浓度、光照强度等环境参数的采集,采用2GB的SD卡实现测试数据的海量存贮,LCD12864作为系统显示屏,显示界面包括系统状态主界面、参数状态设置、报警信息、24h内极值数据查询等,系统键盘采用按键、旋钮和电位器组合实现,设计完成的气肥反应器控制模式具有手动、自动、智能3种控制模式。

英文摘要：

A carbon dioxide control system takes Arduino Mega 2560 as the main controlling kit,and the sensors of AM2301,CM1101 and BH1750 were respectively used to detect temperature and humidity, carbon dioxide gas concentration and light intensity in the greenhouse. The 2 GB SD card was used for mass storage of test data. The I.CD 12864 was used as display kit for the control system. The system interface includes the main interface,parameter settings interface,alarrrLs interface, extremes data queries within 24 hours etc. The system keyboard uses buttons, knobs and potentiometers. The gas fertilizer reactor control mode includes manual control,automatic control and intelligent control.
