Abstract: In conflict-affected and infrastructure-deficient areas, such as the eastern Democratic Republic of Congo (DRC), military troops face significant health hazards without reliable access to medical services or communication systems. This paper outlines the design and implementation of an autonomous Internet of Things (IoT)-based medical monitoring system that operates independently of internet access. The system incorporates low-power embedded technologies, such as the ESP32 WROOM-32UE microcontroller, DS18B20 temperature sensor, Polar H9 heart rate monitor, Neo-6M GPS, and SIM800L GSM module, to provide real-time monitoring of vital signs and geolocation of soldiers in the field. Data transmission occurs over SMS, guaranteeing uninterrupted functionality in faraway areas. The suggested system prioritizes energy efficiency, immediate reactivity, localized alarm production, and modular scalability. Thorough system testing and deployment simulations demonstrate its ability to enhance wartime situational awareness and facilitate prompt medical interventions for frontline personnel.
