IoT Based ECG Monitoring with AD8232 ECG Sensor and ESP8266

With the rapid development of IoT technology, considerable advancements have been made in the field of telehealth and remote health monitoring. This paper proposes the design and implementation of a small, economical, and portable ECG monitor for use in home health care. In this proposed design, the AD8232 ECG sensor is used as an analog front end to detect and condition the weak electrical signals generated by the heart. These conditioned signals are further amplified and converted to digital form using the ESP8266 microcontroller. The ESP8266 microcontroller, with its integrated Wi-Fi connectivity, transmits the obtained ECG signals to the IoT cloud platform (ThingSpeak). This ensures real-time monitoring of the heart activity, enabling early detection of any abnormality in cardiac function.
