Agricultural environment information collection system based on wireless sensor network

In order to realize intelligent perception, intelligent warning and intelligent decisions-making of the agricultural production environment, this paper introduces an agricultural environment information collection system and designs specialized sensor nodes. This system adopts μC/OS II for multitasking management. For enhancing the performance of the system, optimization in line with demand is applied to the OS. μC/GUI is transplanted to build a friendly touchable graphical user interface. The proposed system integrates technologies of the Micro-Electro-Mechanism System, system on chip, wireless communication and low power consumption embedded technology, realizing the performing of functions of data collection, processing and transmission. Thus real-time collection, illustration and transmission of the temperature, humidity and other environmental information in agricultural greenhouses can be completed. The designed system based on Wireless Sensor Network provides a new approach to the realization of modern intelligent agriculture.
