ABSTRACT

In order to solve the problems existing in the water-saving irrigation monitoring system, such as small monitoring area, complicated wiring etc., a soil information monitoring system of water-saving irrigation based on Fuzzy PID control strategy was designed. The wireless sensor node is developed with CC2530 as the core, and the real time monitoring of temperature and humidity in soil environment is completed. The system adopts ZigBee technology to realize wireless sensor network and automatic gathering of monitoring data, realizes soil temperature and humidity adjustment based on fuzzy PID control technology, and adopts embedded database management mode to realize terminal node and data management and so on. Compared to the other network monitoring technology, this system is characterized with flexible configuration, which can be widely used in the place unattended or in poor condition. The test run results have shown that this system had many advantages such as low power consumption, flexible networking, scalability, friendly interface, etc.
