Visual Health Track Monitor

During the COVID-19 pandemic, the need for remote patient monitoring became critical due to hospital overcrowding and the high risk of infection transmission. This study presents the design and implementation of the Visual Health Track Monitor, an Internet of Things (IoT)-based biomedical device developed to enable contactless, continuous monitoring of vital signs including oxygen saturation (SpO2), body temperature, and pulse rate. The system integrates the MAX30100 and MLX90614 sensors with an Arduino Uno microcontroller, an OLED display, and an HC-05 Bluetooth module to transmit real-time health data to a mobile application. Alerts are generated automatically in response to abnormal readings, enabling timely medical intervention. The proposed device enhances telemedicine infrastructure and addresses key limitations in conventional patient monitoring by minimizing direct contact while ensuring accurate physiological assessment.
