Building Heart Rate Monitoring Devices with Pulse Sensors with an Arduino Uno and Bluetooth Module

For severely ill patients suffering from organ system failure, efficient heart rate monitoring is essential. Digital heartbeat devices and pulse testing are examples of traditional techniques. Early identification of heart illness and failing heart valves is made possible by cardiac monitoring, especially auscultation with electronic stethoscopes. The advantages and disadvantages of employing the heart rate monitoring sensor have been thoroughly discussed in this study. In this study, we use the Bluetooth module to see or recognize the different heartbeats of different persons. The same results that are obtained from the Bluetooth module are also displayed on the liquid crystal display (LCD).
