This article presents an interesting Internet of Things (IoT) cold storage management system
designed to preserve tomatoes and onions. The system provides precise environmental
management to avoid rotting and prolong the shelf life of perishable products by integrating
sensors for temperature, humidity, and gas. Important environmental factors are regularly
monitored by sensors positioned strategically throughout the storage facility. While gas sensors
identify ethylene and other ripening gases and trigger ventilation or ethylene removal systems
to slow down ripening and prevent premature spoilage, temperature and humidity sensors
maintain ideal conditions for both tomatoes and onions. For real-time analysis, the gathered
sensor data is sent to a central IoT platform. To maintain ideal storage conditions, sophisticated
algorithms dynamically modify ambient elements, including temperature and humidity. When
there are anomalies, the system takes the initiative on its own to maintain freshness. The system
provides real-time access to storage conditions through remote monitoring and control via web
or mobile interfaces. Strong security protocols ensure confidentiality and data integrity while
guaranteeing adherence to privacy laws and preventing unwanted access. The system's
effectiveness in improving post- harvest storage procedures, cutting energy use, and
minimizing food waste is demonstrated by extensive testing. This solution, which improves
food security and sustainability in agricultural supply chains, uses IoT technology and sensor
integration to offer a dependable, sustainable approach to cold storage management.
