IOT-BASED AUTOMATIC IRRIGATION WATER GATE SYSTEM WITH SOLAR PANEL POWERED MPPT POSITION SENSOR

Abstract

This invention relates to an Internet of Things (IoT) based automatic irrigation sluice gate system that is capable of operating independently using a solar panel power supply with precise door position control. The system utilizes a 550 Wp solar panel optimized with Maximum Power Point Tracking (MPPT) to charge a 12V 100Ah VRLA battery, then powers a Siemens S7-1200 PLC, Raspberry Pi 4B, 4G LTE modem, sensors, CCTV, and motor actuators via a Schneider contactor and 24VDC PSU. The door opening position is read continuously by an Omron E6B2-CWZ6C rotary encoder and its limits are monitored by a Fotek PM12-04N proximity sensor as a digital limit switch. The Raspberry Pi runs a Node-RED dashboard that can be accessed remotely to monitor energy telemetry, door status, and select OFF, MANUAL, or AUTO operation modes, while sending OPEN / CLOSE / STOP commands with visual verification via a V380 Pro CCTV.This invention improves the efficiency, safety, and reliability of irrigation management, especially in remote agricultural areas that are not reached by the PLN electricity network.
