Water-saving Irrigation Control System Based on Wireless Sensor Network

In order to improve the utilization of irrigation water,and ease the growing tension of water conflicts,a water-saving irrigation control system is introduced,which integrates the ZigBee wireless sensor network technology and GPRS network,designs wireless nodes based on CC2530.The system,which is controlled by single chip microcomputer has four major components: wireless sensor nodes,wireless routing nodes,wireless gateways and control centers.It can be real-time moni-toring of soil temperature and humidity changes,and it is based on soil moisture and crop water law for precision irrigation.The system automatically controls water based on crop irrigation water,which can help to improve the utilization rate of agricultural irrigation water and the low level of automation of irrigation systems.
