Heart is the important part in our body that works to pump the blood to every part
in human?s body. One of way that used by medical personel to know about our
healthy is checked the heart rate. Therefore, we made device to calculate the
heart rate as the facility to make easy in work for medical personnal.
The heart detector has made based on arduino and show on LCD 16x2
and smarthphone by buetooth connection. The purpose in making this research is
to make easy in knowing people?s heart beat.
As a comparative data for heart rate sensor and oxymeter with difference
between the two systems of 2 BPM on the fingers, the comparison of average
error rate is 1,19% and the accurate rate of device made in this research arround
96,5%
