IOT Based HealthCare Monitoring System

ABSTRACT: This paper dives into the design and taking advantage of wireless connectivity, these implementation of a Health Monitoring System (HMS) that utilizes the ESP32 microcontroller. The system is designed to keep a constant eye on essential health metrics like heart rate, blood oxygen saturation (SpO₂), and body temperature. By taking advantage of the ESP32’s energy efficiency, processing power, and wireless capabilities, the HMS provides real-time, dependable, and budget-friendly health tracking. The setup combines physiological sensors with output devices such as LCDs or LEDs to visualize data and send alerts. To ensure that data remains secure and private, it employs encryption protocols, digital signatures, and checksums. This innovative system aims to improve early diagnosis and prompt medical intervention, ultimately enhancing patient care.
