Automatic water table control system with remote telemetry and control unit

Abstract

A newly developed automatic control system effectively manages water tables using perforated pipes for both irrigation and drainage. Water levels are monitored by sensors connected to a Remote Telemetry Control Unit (RTCU), which operates irrigation and drainage valves. The system links to a cloud server, providing remote access through a user dashboard. This enables users to observe water level data and adjust the water table as needed. The system's adaptability allows for regulation of rice field water levels based on cultivation requirements, enhancing water use efficiency, sustainability, and environmental friendliness. Operating at a laboratory scale for several months, the system's performance in controlling water tables has been assessed using recorded data. The data reveal that the system automatically provides irrigation when water tables decrease and initiates drainage when rain increases water levels or when a lower level is set. This control ensures optimal soil moisture preservation, readily available to plant roots. Overall, the system demonstrates strong performance in maintaining water tables and soil moisture levels
