You come to the right place, i.e., Circuit Uncle, if looking for a heart pulse rate sensor to buy online in India! This Hear Pulse Sensor is a low cost, a compact, light-weight, and a plug-and-play alternative to ECG which could be used with an Arduino and Raspberry Pi. It is very popular among the students and sports researchers of India, who what to sense the heartbeat rate and other effects on their wearable projects. With an ECG you can do it, but they are costly, and very inflexible, as you cannot make your own automated applications with them.

The sensor is basically an optical heart rate sensor that measures pulse electronically. The voltage generated across the sensor changes with the volume of a blood vessel which varies with the heart pumping the blood. The heartbeats are detected by measuring the change in volume using an optical sensor and a green LED. The LED on the front side of the sensing side of the sensor is placed directly over a vein in our body, e.g, Fingertip.
