This paper presents the development and evaluation of an IoT-enabled smart helmet designed to enhance worker safety and site productivity in high-risk construction environments. The primary objective is to mitigate fall-related and heat-related risks commonly faced by laborers in the Gulf region. The proposed system integrates GPS, temperature–humidity (DHT11), and motion sensors (MPU6050 gyroscope and accelerometer) into a compact, wearable unit capable of real-time data transmission. A key technological novelty is the embedded fall detection mechanism, which analyzes sudden movement patterns to trigger instant alerts, enhancing response times during critical incidents. A fall detection algorithm was developed to identify abnormal movement patterns and trigger instant alerts, while continuous temperature monitoring addresses risks of heat stress in extreme climatic conditions such as Dubai, where temperatures exceed 45 °C. Field trials and simulations confirmed the feasibility of the system, demonstrating reliable data transmission, accurate fall detection, and effective remote monitoring. The solution is coupled with a rental-based business model, making it cost-effective and scalable for contractors. The findings suggest that the proposed helmet provides a practical and scalable safety solution.
