Real-time IoT-based Temperature Monitoring and Analysis System for Refrigeration Equipment for Preventive Maintenance

Abstract

Cooling systems are vital in maintaining product quality across various industries, including food, pharmaceuticals, and manufacturing processes. However, when cooling systems experience problems from inefficient operation or inability to cool properly, this can result in product damage. For this reason, the research team has developed a real-time cooling system temperature monitoring and analysis system using IoT, applying ESP32 and DS18B20 to enhance preventive maintenance efficiency. The system can monitor cooling system operations in real time by using DS18B20 temperature sensors and ESP32 microcontrollers. Furthermore, it can record temperature data, analyze trends, and provide immediate alerts when abnormal temperatures are detected, allowing the technical team to instantly identify which installation location is experiencing problems and enabling timely on-site resolution. Additionally, it reduces the workload of manual temperature measurement and monitoring by employees, which could lead to errors. Implementing this real-time cooling system temperature monitoring and analysis system using IoT will help reduce product damage from abnormal cooling system operation, increase customer satisfaction, and improve overall operational efficiency.
