IoT based Message Alert System for Emergency Situations

Abstract

An alarm is an audio or visual signal to alert people of a problem, danger or something undesirable. Some alarm systems are used for security purposes during producing warning signal in form of sound, light or send alarm message to warn people of a particular danger. In this research a framework of mobile emergency alarm system (MEAS) is proposed. The system consists of two parts: Transmitted and Central emergency. The aim of the first part is to detect the event, its type and trace the location using global position system (GPS) receiver device, furthermore it sends all these gathered information’s as SMS message to central emergency part using Global system for mobile communication (GSM). The aim of the second part is monitoring and analyzing the alarm message and finding the nearest helping center. The system uses Arduino microcontroller R3, sound sensor and three push buttons for (fire, car accident and earthquake). Internet of thing (IOT) is used in this system to send and receive the alarms between the transmitted part and central emergency part. The proposed system follows the object-oriented software engineering (OOSE) approach using unified modeling language (UML).
