Abstract
Inefficient irrigation practices and the absence of real-time field monitoring contribute significantly to water wastage and reduced agricultural productivity. Manual irrigation methods rely heavily on human judgment, often resulting in over-irrigation or water stress conditions for crops. This paper presents an IoT based smart agriculture system designed for automatic irrigation, soil moisture analysis, and crop health monitoring. The proposed system integrates soil moisture sensors, water level sensors, and an ESP32 microcontroller to automate irrigation based on real-time field conditions. A relay-controlled pump motor ensures efficient water usage while preventing dry-run damage. In addition, an ESP32-CAM module enables real-time remote crop monitoring through live video streaming. Experimental implementation demonstrates that the system reduces water wastage, minimizes human intervention, and enhances irrigation efficiency. The proposed solution offers a lowcost, scalable, and sustainable approach suitable for modern smart farming applications.
