Design of Agricultural Automatic Irrigation System Based on ZigBee

In recent years，with increase of population，rapid development of economy and continuous improvement of urbanization，contradiction between water resources is becoming more and more serious，and water is an indispensable factor in agricultural production.At present domestic agricultural irrigation system is mostly by manual operation，time-consuming and waste of water resources，the result is not satisfactory.Part of the irrigation system is advanced，but the practicability is not strong.Therefore，an automatic agricultural irrigation system based on ZigBee wireless sensor network technology was designed.Working principle，software design and hardware structure of system were introduced，and future development prospect was also described.
