Internet of Things-Based 3-Lead ECG Signal Acquisition System

IoT, also known as the Internet of Things, has been a promising technology that involves numerous devices worldwide to stay connected to collect, share and analyze data, thereby building invocations that can help humanity. The IoT-enabled system consists of a smart device connected to processors, sensors, and communication hardware to receive data from the environment, process it into digital signals, and transfer it to devices for analysis. Internet of Things-Based 3-Lead ECG Signal Acquisition System is an efficient trio of components. It is a patient-centric monitoring system, which allows them to actively collect real-time rhythmic contraction and relaxation of cardiac muscles as signals and store the data in the database. It can then be analyzed using personal devices like laptops and smartphones. Providing a window for actionable insights in cases of emergencies. In this paper, we have constructed an IoT-based ECG system by taking into account the basis of ECG mechanism. It obtains impulses via electrodes from specific locations on the body as input for the AD8232 sensor operating at a supply range of 2–3.5 V. The sensor filters biopotential signals, amplifies them, and transfers them to the microprocessor (Arduino board Uno). The board obtains the signals from the sensor and, as per the instructions given via the code through the compatible software, it processes the signals, and sends them as an output for visualization by the system connected to the board. The system produces an ECG pattern in the Arduino Ide Serial plotter and provides heart rate and heart rate variability. The values can be obtained from a serial monitor and are analyzed using different applications. IoT-based ECG can be incorporated into ambulances for diagnosing various cardiovascular conditions of the patients remotely by the doctor.
