Description
The IoT Heart Attack Detection & Heart Rate Monitor is designed to continuously monitor a person's heart-related parameters and send the readings to an IoT dashboard or mobile application. The system can use a MAX30102 sensor to measure heart rate and blood oxygen saturation, while an AD8232 ECG module can be used to acquire basic ECG waveform data. An ESP32 processes the sensor information and displays the measured values on an OLED or LCD screen. The system can be programmed with alert conditions so that when the monitored values cross predefined limits or abnormal patterns are detected, a buzzer and remote IoT notification are activated. An emergency button can also be added so the patient can manually request help. This project is useful for remote health monitoring and educational demonstrations. It should not be treated as a medical diagnosis system unless clinically validated and certified.
