Abstract

This work focused on the Heart Beat Monitoring Module and the concepts of IoT to implement the required system to measure the heartbeat of a patient remotely without the need of a staff nurse. Some elderly person live alone and there is a need to monitor heartbeat at every moment. In this research, we measured the pulse rate of the person at every minute, transmitted the data over the internet and interfaced with the user via. our Android app. This heart-beat sensor includes a computing circuit, timer circuit in order to measure pulse rate, heart beats and temperatures etc. The Internet of Things (IoT) equipped with microcontrollers and sensors can give an easy and cost-effective remote health monitoring. The software involved was the Android Application developed using Android Studio, which is the Integrated Development Environment (IDE). This app retrieved the data from the open IoT platform thingspeak.com. The software involved in this project was the Android Application developed using Android Studio, which is the IDE for Android Applications. This app retrieved the data from thingspeak.com. ThingSpeak is the open IoT platform with MATLAB analytics. The user can enter the channel number or the API key of the ThingSpeak to access the graphs and pulse readings via his phone application. The hardware of Arduino is an arduino uno circuit board with a software program. The chip of this circuit board is programmable to send programmed data first to the microcontroller and then to the specific required multiple circuits to execute required series of commands. A highly sensitive PulseSensor was used to measure the heartbeat of the patient automatically. An Arduino Uno microcontroller interfaced with a Wi-Fi module ESP8266 used to transmit pulse reading over the internet using Wi-Fi. The heartbeat was displayed on the LCD of the patient in run-time. The heartbeat in beats per minute (BPM) was plotted against time (min). A mounted pulse sensor to the patient had monitored the heartbeat and transmitted it in the form of voltage signal to the microcontroller, which converted it back into a mathematical value. The Arduino transmitted the data onto the thingspeak.com portal, where it was plotted on a graph and the values were stored for future assessment. The user of the app was given a thingspeak API and the channel number as an access code, through which physician or nurse can accessed the patient’s data. IoT based heartbeat module as an android application can provide a convenient, cost effective and continuous remote measurements for heart patients. This app can reduce the burden of hospital visits or admissions for elderly patients. Our IoT based handy heartbeat module as an android application will provide a convenient, cost effective and continuous remote measurements for heart patients. This app can reduce the burden of hospital visits and admissions for elderly patients. Doctors and nurses can frequently be updated through this app for patient care. In future, health based IoT in medicine will significantly improve patient quality of life from real-time measurements.
