India is the world's second largest producer of onions. Among other fruits and vegetables, the onion is extremely important not only as a vegetable but also as a foreign exchange earner. However, because of the constant changes in the Indian climate, onions can rot or decay. As a result, onions should be stored at the temperature recommended by the National Onion Association (NOA). The onions are stored in ambient conditions at temperatures ranging from 0 to 4°C and humidity levels ranging from 60 to 70%. So the idea of preserving onion has arisen. In this project, we created an onion preservation system that preserves an onion in a specific way. Temperature and humidity sensors have been used in this system to monitor temperature and humidity, respectively. By utilizing the Peltier module, to maintain the standard temperature range, the air inside the tank is cooled and warmed. The proposed system will be smart and efficient thanks to the use of the Internet of Things (IoT), and the user will receive system notifications from anywhere.
