Design of a Real Time Auto Water Saving Irrigation System Based on μC/OS-II and Zigbee Network

The increasing shortage of water around the world today is an important problem, so an efficient water management is very important especially in agriculture field. There are many embedded platform based irrigation control systems are available, but the major drawback of such systems are their inability to handle multiple tasks. The reliability and processing capability of the systems are greatly improved by adding the Real Time Operating System (RTOS), that provides real-time multi-tasking capabilities to the system. This paper proposes an embedded platform based on μC/OS-II RTOS and Atmega128 AVR microcontroller, which has a Wireless Sensor Network (WSN) using ZigBee technology, for real time in field sensing and control of an irrigation system.
