Real-Time Heart Rate Monitoring Using Arduino and Pulse Sensor

In addition to monitoring blood pressure, cholesterol levels, lifestyle habits, and medical history, heart rate also serves as an essential measure in assessing overall health. The heart rate is a crucial indicator of health and is closely related to the functioning of the cardiovascular system. The objective of the study is to develop a prototype that can measure and display the heart rate using a pulse sensor and an Arduino IDE. The heart rate is calculated by analyzing the pulse sensor's reading. In order to detect irregular heart rates, threshold checks are included. If the heart rate exceeds the predetermined threshold value, the LED and buzzer will be activated. If the heart rate is within the normal range, the system will display "GOOD" while "BAD" will be displayed if the rate is not in the allowable range. In order to alert the user and prompt them to take the appropriate action, the LED and buzzer will sound when the reading falls outside of the specified range. The prototype effectively accomplishes its goal of monitoring, displaying, and warning the user in case of an unexpected and possibly harmful spike in heart rate, particularly when engaging in physical activity or exercise.
