Abstract
In times of natural disasters like earthquakes, floods, landslides and cyclones, the normal communication lines are frequently cut, thus reducing the ability of the affected people and the relief team to communicate vital information. Cellular networks and Internet-based communication systems could be compromised in the event of a loss of power, damage to infrastructure or network congestion. Thus, it is necessary to have a communication system that will be dependable, low power, and infrastructure independent that can function during an emergency. This paper introduces the design and development of a bidirectional communication system for disaster management and emergency communication based on LoRa technology. The proposed system utilizes an ESP32 microcontroller as the brain and a LoRa transmitter-receiver module for long-range wireless data transfer. It features a built-in Neo-6M GPS module for real-time location and a keypad for setting and sending personalized messages. Transmitted and received messages, device status and location information are displayed by an OLED display. Also, there is an SOS button provided for sending out alerts instantly and the user’s location. The system is also solar powered to eliminate reliance on traditional electrical systems in remote and disaster areas. The transmitted data (messages, GPS coordinates) is also uploaded to the cloud platform ThingSpeak if the internet connection is available, which allows data to be stored, displayed and monitored remotely. The proposed system is a cost effective, energy efficient, and resilient communication system that can be used to support emergency response operations in challenging environments. The system integrates long-distance communication, location tracking, disaster emergency alert, and solar energy power support, allowing for better situational awareness, collaboration among users, and effective disaster response and recovery.
Keywords: LoRa, ESP32, Disaster Management, Emergency Communication, GPS Tracking, IoT, Solar Power, ThingSpeak, Long-Range Communication.
