Development of Pulse Detector by Using Arduino

Abstract

Taking your pulse is as simple as holding a finger to your neck or wrist and timing the beats with your watch. But if you want to record the data or use it to trigger events, you need to turn that mechanical pulsing action into an electrical signal. This pulse sensor fits over a fingertip and uses the amount of infrared light reflected by the blood circulating inside to do just that. People tend to neglect their own health in order to get job satisfaction. Therefore, they are always stressed with the workload. When stress, there will be an abnormality on heartbeat rhythm due to an increase in heartbeat rate, and thus, exposing themselves to heart diseases. The objective of this project is to develop a device that can be used by the office worker, lecturers, students and et cetera to monitor their heartbeat, conveniently. The importance of the project is to help them monitored their heartbeat from time to time and gave alert about their health so that they will aware of their heartbeat and immediately took action from stressing themselves. For this system, the pulse sensor circuit is attached at the fingertip. The system will operate by sensing the heartbeat of the user and display their current heartbeat through the Liquid Crystal Display (LCD). Then, the LED will blink and the buzzer at the device will immediately alert the user that they are in maximum heartbeat state. So, the LED and the buzzer will help to warn the them to take immediate action by leaving their workload until they are in normal heartbeat. Hopefully, this device will be able to help those needed to monitor their current heartbeat rate from time to time.
