The GSM Health Monitoring System is a real-time patient health monitoring solution developed to continuously observe important physiological parameters and support early risk detection. The system is built using an ESP32 microcontroller integrated with multiple sensors, including the MAX30102 sensor for measuring heart rate and blood oxygen saturation (SpO2), a DHT11 sensor for monitoring body temperature, and an ECG sensor module for capturing basic cardiac activity signals. The measured values are displayed locally on an OLED display and are also transmitted to a live web dashboard hosted by the ESP32, enabling remote monitoring through any device connected to the same network. The dashboard updates readings in real time and uses threshold-based logic to analyze the sensor values and classify the user’s condition as Normal or Risk. This system offers a compact, low-cost, and efficient solution for continuous health observation in home care, clinics, and patient monitoring environments, where timely alerts and early identification of abnormal health conditions are essential.
