Abstract
Ultraviolet (UV) radiation poses significant health risks to outdoor workers, including skin damage, eye disorders, and increased cancer risk. Existing protective measures, such as sunscreen and clothing, are often insufficient or inconsistently applied. This study addresses this gap by developing a Passive Infrared (PIR) system designed to detect harmful UV exposure and alert workers in real-time. The system integrates PIR sensors, UV sensors, and a microcontroller-based alarm mechanism, ensuring timely warnings to prevent overexposure. Findings from laboratory and field tests indicate that the system effectively detects UV intensity variations and enhances compliance with protective measures. The results suggest that implementing PIR-based safety systems in occupational environments can significantly reduce UV-related health risks, improving worker safety and productivity.
