Implementation of Internet of Things Based Heart Monitor Using Electrocardiogram (ECG)

Abstract

This project aims to implement electrocardiogram (ECG)-based Internet of Things-based heartbeat monitoring. When each component selected for execution was tested and linked in compliance with the voltage division rule, the operation was carried out to confirm that a 6-volt supply could power the total of all the circuits supplied for the work. It was a lengthy process because most of the design was not fully understood. The circuit adhered to the intended circuitry to define all voltages and component interfaces. The electrodes were used as probes after the circuitry had been connected correctly to ensure that signals were detected.
They were placed on either side of the area around the Heart, and the device was then used to measure the different levels of signal penetration across the body. After the controller module analyzes the ECG signal received from the ECG monitoring node, it sends data to the Wi-Fi module. This MCU handles the ECG signal, primarily comprising four steps: packetizing, buffering, ADC, and sampling. Using ADC and sampling, the analog ECG signal is first converted to a digital representation. After a brief period in the buffer, the ECG data are packaged according to a specific format. A Universal Synchronous/Asynchronous Receiver/Transmitter (USART) is used to transmit the data to the Wi-Fi module. The established system performed as intended, and the desired outcomes were attained.
