SMF – Industrial IoT Safety & Access Control System

SMF is an in-house industrial IoT system designed to improve worker safety and access control in factory environments.

The system integrates ESP32-based wearable devices with a secure backend to monitor worker status, detect safety incidents, and enforce access policies in real time. All data is processed and stored on-premises to meet industrial reliability and data sovereignty requirements.

Core Objectives

• Real-time monitoring of worker safety status
• SOS alert handling and wearable removal detection
• Role-based access control for restricted areas
• Auditable event logging for safety compliance
• Modular backend architecture supporting multiple indoor tracking methods

System Overview

• Wearables: ESP32-based devices worn by workers
• Backend: Spring Boot application providing RESTful APIs
• Security: JWT-based authentication and role-based authorization
• Database: PostgreSQL for persistent storage
• Frontend: Mobile application for safety officers and administrators

Notes

This project is developed as part of a university coursework submission and focuses on backend system design, reliability, and maintainability.
