Intelligent Grain Storage Management System based on IoT

India is an Agriculture country where 70 % of the population depends on farming, the storage of grains plays a crucial role in national economy. During the grain storage, temperature, humidity and carbon dioxide concentration are major ecological factors that can influence the quality of the stored grain inside the go-downs and warehouses. The traditional methods are limited to simple manual temperature and humidity testing which are relatively backward as the other factors have to be checked and monitored independently for contributing to their effective storage and maintenance. The Real-time monitoring of the grain storage system is designed by using DHT11, MQ2, MQ135 and PIR sensors based on IoT. Also the Blynk application will regularly update the system through notifications in continuous time stamps. The experimental results shows that the intelligent grain storage management system designed in this paper has several good features such as realtime online detection, regular updation and easy system maintenance. This improves the level of grains storage, reduce the grain losses during storage procedure and also reduce man power and labour intensity.
