A LoRa and GSM-Integrated Smart Emergency Watch System with Real-Time Tracking

Abstract

Ensuring the safety of vulnerable groups such as women, children, elderly individuals, tourists, and hikers has become increasingly critical in today’s rapidly evolving world. Safety concerns are exacerbated in environments where access to reliable communication networks is limited or unavailable. This paper presents Safe Connect, a versatile, wearable emergency alert device that integrates LoRa (Long-Range communication), GSM (Global System for Mobile Communication), and GPS (Global Positioning System) technologies to provide real-time emergency alerts and accurate location tracking [1]. Unlike conventional safety systems that rely solely on cellular networks, Safe Connect employs LoRa as the primary communication method for long-range alerts, making it highly suitable for rural or remote areas with poor cellular coverage. GSM acts as a backup, ensuring SMS alerts can be sent when LoRa is unavailable [2]. Additionally, the system features a camera module (ESP32-CAM) that captures real-time video footage and stores it locally on an SD card, which can later be retrieved as evidence. The system is designed to cater to a wide range of users, including women, tourists, children, elderly individuals, and hikers, offering a comprehensive and reliable solution that operates in both urban and rural environments. Testing demonstrates the device's ability to provide reliable alerts, real-time tracking, and robust performance in diverse conditions, making it an essential tool        for           enhancing             personal safety     across                multiple demographic groups
