Abstract In order to solve existing problems of excessive irrigation and waste water in hill orchard,a technology of water-saving irrigation was studied.A design of hilly orchard irrigation control system based on wireless sensor networks was proposed combined with wireless sensor network technology.It took single-chip ATmega128L as the control core,including host computer,sink node,wireless sensor node,soil moisture sensor and solenoid valves.Soil moisture sensor and solenoid valves were connected to wireless sensor node.Data was transmitted by wireless style between sink node and wireless sensor node.Sink node was connected to host computer by RS-232 serial cable.The system can monitor real-time soil moisture of grapes.The system judges whether grape is water shortages according to soil moisture,then send out the irrigation instructions to implement the precise irrigation of grapes.The irrigation automation control of vineyard is achieved.When the soil moisture is reduced to 26.6% in the depth of 25 cm,the irrigation is started for the grape.When the soil moisture is achieved to 45.5% in the depth of 50 cm,the irrigation is stopped for the grape.The experiment shows that the system has achieved precise irrigation and realized water-saving irrigation combining with the survival threshold of grapes.
