IoT Instrumented Food and Grain Warehouse Traceability System for Farmers

In a developing country like India, agriculture is one of the main sectors in terms of income. Good food storage plays a very important role when it comes to food security that is affected by both food loss and food wastage. The losses can be reduced, which will automatically increase the amount of food availability. In this article, we proposed an IoT enabled monitoring system to deploy in remote areas where the accessibility is very minimum for farmers with good storage facilities to reduce food losses and increase food safety. This proposed framework monitors warehouse parameters such as temperature, humidity, CO, motion, vibration, and smoke which is highly affected to grains. The ESP32 WiFi module collects the data from the sensors and this module sends data to Node-red dashboard through MQTT broker. Multiple IoT nodes installed at a different location inside the warehouse and which will give information about the warehouse environment to the farmers through Mobile SMS and E-mail notification.
