Abstract: This project develops an ECG monitoring system using an ESP32 microcontroller and an ECG sensor for continuous heart rate tracking. The system transmits real-time data to ThingSpeak for visualization and sends SMS alerts to a designated guardian if an abnormal heart rate is detected. Designed to enhance patient safety and monitoring efficiency, it is particularly beneficial for individuals with chronic heart conditions, elderly patients, and those in post-operative care.

Keywords: Continuous heart rate monitoring, Real-time data visualization on ThingSpeak ,SMS alerts for abnormal heart rates, Enhanced patient safety, Integration of IoT technologies
