A Case Study on Applying MQTT Communication to Improve Cold Storage Safety and Quality Management

Abstract

This paper investigates the use of the MQTT protocol for monitoring cooling systems and discusses the advantages of this approach. Cooling systems play a critical role in many areas such as the food, pharmaceutical and chemical industries, and their proper functioning is vital for product quality and safety. However, monitoring and managing these systems often presents major challenges. Traditionally, the monitoring of these systems has been carried out by dedicated on-site staff or personnel, which can be risky, time-consuming and costly. The MQTT protocol is a fast and efficient communication protocol designed for data communication between IoT devices. In this study, how the MQTT protocol can be used for monitoring cooling systems and the advantages of this protocol are examined in detail. The use of MQTT can facilitate remote monitoring of cooling systems and thus significantly reduce response and reaction times. Thanks to a web application developed to store and display the data received through the MQTT protocol, it becomes easier to remotely monitor the storage room temperature values and intervene when necessary. End users can instantly view storage room temperatures via phone, tablet or computer and make intervention decisions when necessary.
