Abstract:
The heart rate meter is medical device used to measuring the number of
heartbeats per unit of time, usually expressed as beats per minute (bpm).
.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 comfortable.
This project has been a new integrated, simple and portable device to
provide a monitoring heart rate at the fingertip by using optical sensor
.the implementation of the heart monitor involves low cost amplifier and
filter components coupled with a microcontroller to count the heart for
duration of fifteen seconds and displays the information"HR" on digital
display unit.
The circuit is tested by simulation program then designed practically and
Result is obtained.
