Abstract: This research investigates the design and implementation of a solar-powered automatic soil irrigation system. The system aims to optimize water usage and enhance agricultural productivity by automating the irrigation process and utilizing renewable energy. The system incorporates a microcontroller-based control unit, solar panels for power generation, a water pump, and a network of sensors to monitor soil moisture levels and environmental conditions. The system autonomously adjusts irrigation schedules based on real-time data, minimizing water wastage and ensuring optimal plant growth. The results demonstrate the effectiveness of the solar-powered system in achieving efficient and sustainable irrigation, contributing to increased crop yields and reduced environmental impact.

Keywords: solar energy, automatic irrigation, soil moisture sensor, microcontroller, water conservation, sustainable agriculture, renewable energy, IOT
