Implementation of Soldier Assisting Device using LoRa with SOS Functionality

Abstract

The strength of a nation is in its military powers, including soldiers in air, water, and land. To monitor such soldiers, a small and efficient system is proposed. This system is mountable to the soldier and monitors the health parameters and location of the soldier. Some useful to the soldier are also incorporated into this system, which includes metal detection for landmines and the ability to send an SOS signal to the control room. The implementation of the LoRa (Long Range) technique helps us to transmit the signals from the soldier to the control room with a low data rate, at long distances. By using LoRa we can make a system that is better at consuming low power and transmit at a high transmission power. The health monitoring system comprises of heart rate monitoring, pulse monitoring, temperature measurement, and motion detection. Motion detection helps in the identification of the fatigue levels of the soldier in the war zone. Metal detection is assisted by the use of an Inductive proximity sensor. These combinations of devices help in the effective tracking of the soldier in the field and their parameters, thus contributing to the individual's increased survivability.
