This research examines a driver monitoring system developed using hybrid technologies such as YOLO, CNN, and Haar Cascade, integrating IoT sensors, computer vision, AI, and embedded systems to evaluate driver actions along with vehicular and environmental conditions in real time. By applying deep learning techniques, including CNN and Haar Cascade, the system effectively detects driver fatigue, drowsiness, and distraction. IoT sensors further improve accuracy by capturing physiological and vehicular movement patterns through both wearable and non-wearable approaches, enabling comprehensive behaviour analysis and timely accident-prevention alerts. The study reviews emerging AI-driven driver monitoring solutions and highlights the advantages of AI-embedded detection models implemented with Arduino Uno for efficient sensor data processing. It also discusses challenges related to data quality, computational requirements, and system integration, along with potential mitigation strategies. The conclusion offers recommendations for further research to advance real-time monitoring systems and strengthen road safety.
