Monitoring System of Food Warehouses By Using Single Board Computer

Abstract

Problem arose when the price of the daily consumed foods suddenly increased and the quality dropped significantly due to reinless syndicates and poor food management as the daily news were flooded by the reports in the year of 2022 and 2023 at an alarming rate in Bangladesh. Where investigations of Director of National Consumer Rights Protections described the lack of data records is the prime culprit for the situation. We collected data from different food suppliers from Dhaka to narrow down the problem and create a sustainable solution for the issue which is digitally collecting data by implementing Wireless Sensor Networking System and monitoring the value in real time. Sensors will be installed in warehouses where foods are being stored for collecting data then a single board computer will act like a hub which will send the data to the cloud server so that multiple devices can connect to the server aiming to monitor the real-time value. We created a project using Raspberry Pi 4B as single board computer and DHT 22 sensor for collecting the data of both the humidity and the temperature and ran the project for several months for collecting the value difference. Then we analyzed the outcome which led the conclusion for better waste management, strong monitoring and easy data record that will slow down the issue and will help in total GDP in Bangladesh.
