Utilizing GPS, Node MCU, sensors, and other tools, the Soldier Health and Position Tracking System (SHPTS) is designed to provide soldiers with enhanced safety and security on the battlefield. This IoT-enabled system is mounted on the soldier's body and wirelessly transmits vital information to a control room, such as the soldier's location, health status, and physiological indicators. The system utilizes GPS to accurately pinpoint the soldier's latitude and longitude, allowing for quick and easy location tracking. Furthermore, the system includes physiological sensors that the soldier can wear to monitor their body temperature, oxygen level, and heart rate.
