Smart heart beat rate monitoring system / Munirah Mohd Shamlan and Noor Syazwana Mohamed Zulkhairi

This project describes the design of a simple and user friendly based heart rate measuring device with LCD 16 x 2. Heart rate of the subject is measured from the finger using pulse sensor to detect the flow of blood through the finger. The main analog signal received from the human body gets captured with a pulse sensor. Then the signal is being converted from analog signal to digital signal by using Arduino Uno. The pulses are counted by a microcontroller and the output of the circuit is displayed on the LCD 16x2. This project installation is very easy and convenient for the user especially for the elders that are not good in using electronic devices. The development of heart pulse instruments rapidly fast in market since 21st century. The proposed system is applicable for family, hospital, clinic, community medical treatment, sports healthcare and other medical purposes. Also, fit for the adults and the pediatrics. Heart rate monitoring is extremely essential in order to keep track of one's health. Unlike traditional methods like Electrocardiogram (ECG), which are complicated and non-portable, there is a need for a simple and affordable heart rate measuring device. The performance of heart beat monitoring device was compared with ECG signal represented on an oscilloscope and manual pulse measurement of heartbeat, giving excellent results. Our proposed heart beat monitoring device is economical and user friendly.
