Abstract

The conservation of agricultural products, particularly perishable items like onions, wheat, rice, potatoes, maize, etc., is a critical aspect of ensuring food security and minimizing post-harvest losses. On inspection of farmers, end users face a number of challenges in traditional preservation methods; this study proposes an innovative electronic system particularly for onion preservation. The envisioned electronic system leverages advanced technologies, including sensors and control mechanisms, to create an efficient and automated onion storage environment. The parameters such as humidity, temperature, methane, ethylene, carbon monoxide, and airflow within the storage facility are monitored and controlled in real-time to optimize conditions for onion preservation. The embedded system is designed to adapt to varying environmental factors and maintain an ideal storage environment throughout the storage period. Additionally, the electronic system incorporates smart features, allowing remote monitoring and control via GSM or the Internet of Things (IoT) technology. This facilitates accessibility for farmers and stakeholders, enabling them to oversee onion storage conditions from anywhere, thereby enhancing convenience and efficiency. The proposed onion preservation electronic system aims to extend the shelf life of onions, reduce post-harvest losses, and contribute to sustainable agriculture practices. The integration of cutting-edge technology into onion storage processes holds promise for improving overall food supply chain resilience and meeting the growing demands of a global population. Therefore, an Arduino-based smart electronics system design for early onion spoil detection and the details regarding the design and results are interpreted in this paper.
