Abstract
This paper investigates to compare the
Photoplythsmography (PPG) signals based on Heart
Rate Variability (HRV) criteria for two different age
groups. This paper demonstrates the variation of PPG
and HRV signals for subjects of age group in the
twenties and fifties. The so used Easy Pulse Sensor
module making use of the photo sensing technique to
collect the amount of infra red light passing through the
respective body part (finger tip in this case). After
processing this signal through a series of condition
stages involving low pass and high pass filter, a noise
free PPG signal of adequate level is produced. The
shape, frequency components and amplitude of this
PPG signal depend upon the physiological condition as
well age. This signal is then further processed by using
the Arduino based processing board for being
interfaced to a PC for display on the Graphical User
Interface (GUI). The results are clear indicative of the
physical conditions and age groups.
