Web-Based Data Monitoring for Iiot Using Nodered and Raspberry Pi

This paper presents a low-cost, web-based monitoring system for Industrial Internet of Things (IIoT) applications. The system collects real-time data from a PLC using Node-RED on a Raspberry Pi, stores it in a MySQL database, and displays it via a browser-based dashboard accessible within the local network. This integration of opensource software and affordable hardware enables continuous monitoring, improves operational visibility, and supports decision-making in industrial environments. Results demonstrate that the system functions effectively for both industrial setup, offering a cost-effective solution aligned with Industry 4.0 practices..
