Smart Device to Guide Individuals to Wells in the Desert, Monitor Health Status and Send Emergency Notifications

Abstract

This work describes a smart tool to enhance safety in the Algerian Sahara. It combines GPS wayfinding, vital signs monitoring (heart rate, body temperature), and Thuraya satellite communication for urgent alerts in remote areas. The tool helps locate water, monitors wellness, provides automatic emergency alerts, and uses a solar rechargeable battery. Tested in desert-like conditions, its economic viability is confirmed through market analysis and cost estimates. The device offers a cheap, useful solution for desert explorers, workers, and travelers, with potential in other harsh environments.
