Prototype of an Intelligent Firefighter Helmet with Improved Localization System and Toxic Gas Detection for Wildfire Scenarios

Resumen

Abstract—This paper describes the redesign of an intelligent firefighter helmet prototype aimed at enhancing safety during wildfire suppression in Honduras. Building upon a base system that monitors vital signs (heart rate and blood oxygen), ambient temperature, posture, and location via LoRa technology, the enhanced design integrates several key improvements: a high-speed calibration GPS module, carbon monoxide (CO) detection, and ruggedized thermal and waterproof housing for the electronic components. Furthermore, a redesigned monitoring interface presents both quantitative and qualitative data to provide comprehensive situational awareness for the user and command center. Experimental results demonstrate a GPS accuracy of ±2.5 m, reliable hazardous gas detection, and structural integrity at temperatures up to 85°C. This system improves occupational safety and emergency management by providing real-time data for informed strategic decision-making in wildfire scenarios.
