Abstract :
This paper describes a real-time soil water content monitoring system from both perspectives of hardware and software. The system consists of an ATmega128 microcontroller with embedded μC/OS-II operating system, BD-I-type soil moisture sensors, RS-485 and RS-232 bus-based data transmission technologies. Compared to traditional microcontroller monitoring systems, the reliability and processing ability of the system are improved greatly by adding the μC/OS-II operating system, which brings real-time multi-task processing capabilities. The system has significances in improving water utility efficiency and precise irrigation control in urban greening as well as agricultural and forestry production.
