Design of an IoT-Based Cooling Temperature Monitoring andAlert System for Beef Storage to Maintain Halal Integrity andSupport Community Development

Abstract

This study aims to design an Internet of Things (IoT) system that supports the halal control process of beef through cloud-based temperature monitoring and electrical current detection, contributing to community development efforts. The design utilizes the GY-906 infrared temperature sensor as a non-contact temperature measurement component, the PZEM-004T current sensor for detecting electrical load conditions, the ESP32S microcontroller as the data processor, and the Blynk platform as a remote monitoring interface. At the design stage, the system schematic diagram, device workflow, and data transmission integration to the cloud were developed. The system is designed to display two main parameters—temperature and current—in real time through the Blynk application. In addition, the design includes a notification mechanism as an early warning system when certain conditions that may affect meat quality occur. The results of this study produce an IoT system design that is ready to be implemented in subsequent stages. This design is expected to serve as an initial model for the development of technology-based monitoring systems to support the quality assurance of halal beef and community development across various storage and distribution contexts.
