Onion production and postharvesting are crucial for increased profit and long-term supply to the consumer vegetable market, a key vegetable crop in arid regions. Quality monitoring is a big challenge during storage duration. Onions are known for their short shelf life of 2–3 months. However, farmers can store onions in a suitable environment after harvesting. When they are stored, maintaining a good environment can increase the shelf life to 5–6 months and result in a better price in the market. This review work also includes limitations of current technologies and emerging technologies in Internet of Things (IoT)-based onion storage monitoring systems.
