Abstract - This paper presents a solar and IoT-based health monitoring and position tracking system for soldiers, which utilizes solar energy to power the system and IoT technology to monitor and track the soldier’s health and position in realtime. The proposed system comprises a wearable device, a solar panel, and an IoT-based platform.Thewearable deviceis equipped with sensors to monitor the soldier’s health parameters, including heart rate, blood oxygen and body temperature. The solar panel provides a sustainable and reliable power source for the wearable device, ensuring continuous operation in the field. The IoT-based platform receives data from the wearable device. Additionally, the platform provides real-time tracking of soldier’s positions using GPS technology, enabling commanders to monitor the soldier’s movements and make informed decisions based on their current location. The proposed system has the potential to enhance soldier’s safety and well-being, as well as improve their overall performance in the field.
