This project introduces an affordable, IoT-enabled, hybrid energy-powered grain storage system designed to reduce the 30–40% post-harvest losses faced by small farmers in India. The system monitors and controls temperature, humidity, and pest activity, and supports real-time fumigation using ozone and ClO₂ for safer grain preservation. Powered by solar and wind energy, it ensures reliable operation in areas with limited electricity. The solution aims to cut spoilage by 30%, improve grain quality, and enhance farmer income through sustainable storage technology.
