An Automatic System Design for Orchard Irrigation Based on STM32 and Zigbee Technology

摘要

This study designs an intelligent system, which can achieve automatic irrigation for orchard by wireless manner. The system mainly includes a soil moisture monitor and control unit made up of a variety of sensors, a central control unit based on STM32F103 and the wireless sensor network based on Zigbee technology. First, the soil moisture monitor and control unit measures the real-time data such as humidity and sends the data to the central control unit by a wireless sensor network based on Zigbee technology. The central control unit sends a control command according to data received to the soil moisture monitor and control unit by the same communication way and sends the data about control command, humidity and etc. to the mobile devices over GSM the in the meantime. This is a high efficiency and energy saving system, which has clearly contributes to save labor, conserve more water and increase production of fruit.
