摘要：Persistent aberration of heart rate may be an indication of serious health complications such as Tachycardia, Coronary Artery Disease, and Hypertension. Hence, heart rate monitoring is extremely essential in order to keep track of one’s health. Unlike traditional methods like Electro-cardiogram (ECG), which are complicated and nonportable, there is a need for a simple and affordable heart rate measuring device. This paper expounds the design and working of a device based on the principle of Photoplethysmography. It is an economical, user friendly, and low power consuming device. The performance of the device was evaluated and its results were compared with the reports of conventional heart rate monitors, and the deviation was observed to be minimal.
