Introduction Design Of A Low Cost Portable Heart Beats Monitor Using Infrared Sensor.

For Chapter 3: this chapter briefly explained the method to develop the prototype. This is including the hardware design and software design. The hardware design focus on the designing circuit sensor, signal conditioning circuit and microcontroller circuit. The software design focuses on the development of microcontroller instructions coding using MikroC Pro for PIC software. For Chapter 4: this chapter briefly explained the result for testing method. The data will record into table for easy observation. Moreover, the result will be analyze and discuss to get better understanding about the result. For Chapter 5: this chapter concluding the finding in this project. In addition, this chapter also included the several aspect involve in overall project such as the project achievements and the learning outcomes. Also will be discussed in this chapter is the future recommendation for future study and prototype development CHAPTER 2 LITERATURE REVIEW

2.1 Overview

This chapter briefly explains about the present theory and concept related to the project. This chapter also discuss about the basic construction of the heart rate monitor and the existing related project.

2.2 Introduction of Heart Rate

Heart rate is the number of heartbeats per unit of time, typically expressed as beats per minute bpm. Heart rate can vary as the bodys need to absorb oxygen and excrete carbon dioxide changes during exercise or sleep. The heart rate of a healthy adult [2] at rest is around 72 beats per minute bpm. Athletes normally have lower heart rates than less active people. Babies have a much higher heart rate at around 120 bpm, while older children have heart rates at around 90 bpm. Lower than normal heart rates are usually an indication of a condition known as bradycardia, while higher than normal heart rates are known as tachycardia [3]. The measurement of heart rate is used by medical professionals to assist in the diagnosis and tracking of medical conditions. It is also used by individuals.
