Abstract

This paper proposes a square spray irrigation system that uses PLC as the main control component and Raspberry Pi as the computing and monitoring node, aiming at the problems of overlapping spray areas and low water resource utilization caused by traditional circular spray heads in current agricultural irrigation. The system obtains on-site environmental data through soil moisture sensors, rainfall sensors, water pressure sensors, and inclination transmitters. It installs the NODE-RED application on Raspberry Pi to display data in real time, and calculates the pulse data required by PLC to control the stepper motor based on the obtained data. This further improves the utilization of water resources and realizes water-saving irrigation.

Keywords
