In today’s fast-paced world, the driver’s well-being is paramount, given the challenges they face on the road, including health emergencies and drowsiness. Our proposed prototype, “Enhancing Driver Safety through Sensor-based Detection and Mitigation of Health Risks in Four-Wheelers,” introduces innovative sensor technology to monitor these issues. It includes a heart rate sensor in the seatbelt and an eye blinking sensor above the driver’s eyes, ensuring continuous vital sign monitoring. The intelligent alarm system, with internal and external buzzers, alerts the driver to potential danger. In case of worsening conditions, an automated emergency call is initiated to nearby services for timely intervention. The system also enables gradual deceleration of the vehicle, prioritizing driver safety enhancement, reducing accidents due to health emergencies or drowsiness, and providing prompt assistance on the road.
