Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. This paper describes a technique of measuring the heart rate through a fingertip and Arduino. It is based on the principal of photoplethysmogram (PPG) which is non-invasive method of measuring the variation in blood volume in tissue using a light source and detector. The fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can be amplified and is sent to Arduino with the help of serial port communication. With the help of processing software heart rate monitoring and counting is performed.
