Design and Implementation of Multi-Node Wireless Security and Safety Siren System for Mid-Scale Industry

Abstract

Ensuring safety in industrial environments is a critical challenge, especially in mid-scale industries where hazards like fire, gas leaks, and unauthorized access can pose serious risks. Traditional wired security systems are costly, rigid, and difficult to maintain. In this paper, we introduce a Multi-Node Wireless Security and Safety Siren System designed to improve real-time monitoring, threat detection, and response. The system relies on sensor nodes for continuous surveillance, using nRF24L01 transceivers for communication, an ESP8266 module for cloud connectivity, and RFID-based access control for security. Through testing, we observed that the system achieved reliable data transmission, quick hazard detection (within 1.5 seconds), and seamless scalability. Our approach presents an efficient, scalable, and cost-effective alternative to traditional wired safety systems.
