Alat Monitoring Denyut Jantung Menggunakan Mikrokontroler NodeMCU ESP8266 Berbasis IOT

Abstract

The heart is one of the important organs owned by humans that functions to pump blood throughout the body and accommodate it again after cleaning the lungs. Heart rate or heart rate is an important indication in the health sector that is useful as an effective and fast evaluation material and serves as a tool to determine the health of a person's body. The method of measuring the number of pulses is commonly used by doctors to determine the condition of a person's heart health. Cardiac examination using an electrocardiograph sensor in a hospital is quite expensive. This examination needs to be done significantly, because many things can affect the performance of the heart. Heart rate monitoring using IOT-based nodemcu esp8266 microcontroller is designed to display pulse data in real time and continuously to determine the working condition of the heart. Heart rate beats per minute (bpm) is a parameter to indicate the condition of the heart, and the way to know the condition of the heart is to know the frequency of the heart rate. This heart rate monitoring tool is designed based on the NodeMCU ESP8266 and a pulse sensor to detect heart rate. This study aims to make it easier to find out the heart rate in real time. The NodeMCU ESP8266-based heart rate monitoring tool has been designed with a pulse sensor to detect heart rate. The heart rate data from the monitoring tool is displayed on a 16x2 LCD then it will be sent via a wifi network connection and displayed on the Smartphone. The blynk application is an output that is displayed via a smartphone connected to the internet.
