The increasing need for real-time health monitoring has encouraged the development of affordable and portable biomedical systems capable of tracking essential physiological parameters outside clinical environments. This paper presents the design and implementation of an IoT-enabled health monitoring system that measures heart rate, oxygen saturation (SpO₂), body temperature, and ECG signals using low-cost biomedical sensors. The system integrates the MAX30102 sensor for pulse rate and SpO₂ measurement, the LM35 analog sensor for temperature monitoring, and the AD8232 module for ECG signal acquisition. An ESP32 microcontroller serves as the central processing unit, enabling sensor interfacing, data processing, local display on a 0.96-inch OLED screen, and wireless transmission to the Blynk IoT platform for remote visualization. The developed prototype provides continuous, real-time monitoring with cloud-based accessibility, making it suitable for home healthcare, remote patient observation, and wearable health applications. Test results demonstrate that the system delivers stable and reliable readings comparable to standard health-monitoring instruments, highlighting its potential as a practical solution for low-cost telemedicine and preventive healthcare.
