Abstract

This paper deals with the diagnosis and analysis of heart rate using Pulse sensor. The pulse sensor uses the optical Methodology to detect the blood flow through the index finger and offers the advantage of portability. The principle of Pulse sensor is that a certain amount of light energy from infrared is absorbed by blood cells and the remaining amount of light is transmitted to the photodiode. Based on the amount of light transmitted, the flow of blood can be calculated, which is directly related to pulse rate. A PIC (Programmable Interface Controller) microcontroller (PIC16F877A) is programmed to count the pulse and to display the heart rate digitally on an LCD (Liquid Crystal Display). The important feature of this paper is the use of Fast Fourier Transform (FFT), to analyze the heart rate using the pulse signal and to diagnose heart related diseases using MATLAB tool. The performance of this device was compared with manual pulse measurement of heartbeat and ECG (Electrocardiography) signal represented on an oscilloscope. Finally, the heart related disease can be diagnosed using the obtained result after the analysis of pulse signal.
