Abstract
An electrical device called a heartbeat sensor is used to detect a person's heart rate, or heartbeat pace. The fundamental things we do to keep ourselves healthy are to monitor our body temperature, heart rate, and blood pressure. We utilise thermometers and a sphygmomanometer to check the blood pressure and arterial pressure in addition to measuring body temperature. A heartbeat sensor can be used to monitor heart rate in addition to manually checking the pulse at the wrists or neck. In this experiment, the heartbeat is found using fingertip pulse oximetry. The amount of blood in the fingertip increases during diastole and decreases during systole of the heart. If you could somehow count the number of pulses in one minute, that would be the heart rate in beats per minute. The subsequent pulsing of blood volume inside the fingertip is precisely proportional to heart rate (bpm).
