Abstract: In this paper, we have addressed the issues which relates to loss of soil fertility and waste of water resource in agriculture. We designed irrigation system based on wireless sensor networks and fuzzy control. The system mainly consists of wireless sensor networks and the monitoring center. All of the nodes in Monitoring area collect the information of soil moisture. Soil moisture is considered as input variable of fuzzy logic controller. The monitoring center receives the signals from wireless sensor network node, and output information controls opening and closing time of the valve in crop areas. The results show that the system achieve real-time monitoring of soil on crop growth, give a right amount of irrigation based on crops growth information.
Keywords: water-saving irrigation, wireless sensor network, fuzzy control strategy, sensor.
