This work is on a microcontroller based heart rate valve using fingertip. It is a low cost and portable method that is proposed and implemented to measure heartbeat using the microcontroller device with LCD output. Heart rate of the subject is measured from the finger using infrared sensors. The heart rate is a parameter most significance to medicine, physics and many other fields. The heart rate is closely related to the function and status of the human heart. More than two million people are at high risk of having heart attack. It would be helpful if there was a way for these people to monitor their heart. So, we have a problem. That is the way our project focuses on how we can utilize this problem and find a solution. The heart rate of a person is different depends on the age. The most heart rate measuring tools and environments are expensive and do not follow ergonomics. Here heart is measured by employing the pulse method i.e. blood flow in to the finger. Heart rate for healthy person is around 72 beats per minute, babies have a around 120 bpm, older children have heart rate at around 90 bpm.

CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
According to R.G. Landaeta (2016), heart rate indicates the soundness of our heart and helps assessing the condition of cardiovascular system. In clinical environment, heart rate is measured under controlled conditions like blood measurement, heart voice measurement, and Electrocardiogram (ECG) [H. Shim, 2008] but it can be measured in home environment also [P. F. Binkley, 2003]. Our heart pounds to pump oxygen-rich blood to our muscles and to carry cell waste products away from our muscles. The more we use our muscles, the harder our heart works to perform these tasks- means our heart must beat faster to deliver more blood. A heart rate monitor is simply a device that takes a sample of heartbeats and computes the Beats per Minute (bpm) so that the information can easily be used to track heart condition.
Due to the advancement in Technology in the field of Medical Science it has become much easier to determine different parameters of a patient through electronic machine-like Heart rate, temperature etc. One such electronic device is Heart rate monitoring System.
The heart rate monitor is personal monitoring device that allows subject to measure their heart rate in real time.Heart rate measurement is one of the most important parameters of human cardiovascular system. This project explains how a single chip microcontrollercan be used to analyse heart rate bit signals in real time. A compact sensor is used to monitor the heart beat in analog form. Temperature sensors and heart beat sensors is connected monitor the patient condition. To check the condition of the patient we required thermometer.
The Hardware and software design are oriented towards a single-chip microcontroller-based system. The specialist at a distance can monitor the patient condition so that we can save the life. This system is to be available at reasonable prices. The heart rate of a person is different depends on the age. The most heart rate measuring tools and environments are expensive and do not follow ergonomics.
The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
1.2 PROBLEM STATEMENT
As heart related diseases are increasing day by day, the need for an accurate and affordable heart rate measuring device or heart monitor is essential to ensure quality of health. However, most heart rate measuring tools and environments are expensive and do not follow ergonomics. The proposed Heart Rate Measuring (HRM) device is economical and user friendly and uses optical technology to detect the flow of blood through index finger.
1.3 AIM AND OBJECTIVE OF THE STUDY
The main aim of this study is to build an economical and user friendly and uses optical device for detect the flow of blood through index finger. The objectives are:
- to provide a reliable means of heart rate measurement
- to have the knowledge of optical technology
- to provide an easy means of taking heart rate measurement
1.4 SCOPE OF THE PROJECT
This device provides an accurate reading of the heart rate using optical technology. The device is ergonomic, portable, durable, and cost effective. We incorporated the optical technology using standard Light Emitting Diode (LED) and photo-sensor to measure the heart rate within seconds using index finger. A microcontroller is programmed to count the pulse. The heart rate is digitally displayed on an LCD controlled by the same microcontroller that counts the pulse.
1.5 LIMITATION OF STUDY
As we all know that no human effort to achieve a project goes without difficulties, certain constraints were encountered in the course of carrying out this on heart rate valve using fingertip are as follows:-
- Difficulty in information collection: I found it too difficult in laying hands of useful information regarding heart rate valve using fingertip and this course me to visit different libraries and internet for solution.
- Difficulty in parts gathering: I found it too difficult when gathering electronics parts used for the prototype.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).
1.6 SIGNIFICANCE OF THE STUDY
This research work will throw more light on the best techniques for taking heart rate measurement. This study will also be designed to be of immense benefit to all health personnel.
It will also serve as a guide to whoever that wants to purchase a heart rate monitoring device.
Finally, it will also serve as a useful piece of information for both producers and users of heart rate measuring device.
APPLICATIONS OF HEARTBEAT MONITOR
1. Works as a Digital Heart Rate monitor
- Works as a Patient Health Monitoring System
- Used as a Bio-Feedback control of robotic applications
