ABSTRACT
What does the heart rate signify? It’s a window into your muscles and lungs;
it reveals how hard they are working. Your heart pounds to pump oxygen-
rich blood to your muscles and to carry cell waste products away from your
muscles. The more you demand of your muscles, the harder your heart has
to work to perform these tasks. That means your heart must beat faster to
deliver more blood. The heart rate gives a good indication during exercise
routines of how effective that routine is improving your health. Once only
used by elite athletes, heart rate monitors are now becoming an essential tool
for everyone from the casual athlete to the personal trainer. Heart monitors
provide an easy and scientific measure of the effort you are putting into your
workouts. A heart rate monitor is simply a device that takes a sample of
heartbeats and computes the beats per minute so that the information can
easily be used to track heart condition. Current technology consists of
optical and electrical monitors. The electrical method provides a bulky strap
around one’s chest. The optical method does not require the strap and can
be used more conveniently than the electrical method.
There are many constraints in producing a heart monitor. First, the
technology used to measure the pulse has to be determined. A cost efficient
way of measuring the pulse is the combination of a led and photo-sensor.
