  Abstract


Post-harvest losses in fruits and vegetables due to improper storage remain a major challenge for rural farmers, especially in off-grid areas with unreliable electricity. This research presents a Smart IoT-Based Solar Powered Refrigerator designed to provide sustainable cold storage using solar energy and intelligent monitoring. The system integrates an ESP32 microcontroller, DS18B20 temperature sensors, an MQ-6 gas sensor, Peltier cooling modules, and a solar charging unit with battery backup. Real-time monitoring is achieved through a locally hosted IoT dashboard and LCD interface. The system automatically regulates cooling, monitors spoilage gases, and manages battery health, significantly reducing losses and enhancing produce shelf life. This paper discusses the system design, implementation, results, and feasibility for rural agricultural deployment.
