    GoSafe is an innovative Internet of Medical Things (IoMT) device designed to improve safety, mobility, and health monitoring for individuals with visual impairments. This wearable system incorporates Arduino-based processing, ultrasonic sensors for obstacle detection, and the MAX30102 optical sensor for continuous monitoring of vital signs, including heart rate, oxygen saturation, and skin temperature. Real-time alerts, delivered through vibration and audio feedback, enable users to navigate safely while maintaining health oversight. Health data is seamlessly transmitted via Bluetooth to a mobile application, allowing caregivers to monitor users remotely and receive immediate alerts in case of abnormalities. Performance evaluations demonstrate GoSafe's reliability and precision. Heart rate monitoring showed a negligible deviation of 0.5%, while SPO2 and skin temperature measurements achieved deviation margins of 0.18% and 0.2%, respectively, when compared with medical-grade devices. Testing across multiple participants confirmed its consistent accuracy and robust functionality. With its modular and scalable design, GoSafe is adaptable for future advancements such as GPS integration and machine learning-based analytics. By combining mobility assistance with proactive health management, GoSafe empowers visually impaired users to navigate independently and securely, while ensuring continuous health monitoring. This dual-purpose device is a major advancement in assistive technology, connecting healthcare needs and accessibility in a practical and affordable way that supports the United Nations Sustainable Development Goal (SDG) 3 by ensuring healthy lives and promoting the well-being for individuals with impairments.
