Development and Design of Greenhouse Testing and Control System Based on Wireless Sensor Networks

ZHANG Bao-hua,LI Shi-ning,TENG Wen-xing,ZHANG Yao-wei(College of Computer Science,Northwestern Polytechnical University,Xi'an 710072,China)  
Considering the problems of current greenhouse control system,which is weak at expansibility and intelligentization,hardware and software of greenhouse testing and control system based on wireless sensor network are designed after analysis of the characters of wireless sensor network.Designed with sensor-node and sink-node,along with temperature sensors,humidity sensors and light-intensity sensors used,the hardware can examine each greenhouse environment parameter automatically.Meanwhile,software realizes its functions of data collecting,data processing and controlling output under the guide idea of modularization.With good utility and expansibility,this system is easy to operate.
