XD-58C Pulse Sensor

XD-58C pulse sensor module is used to measure heart rates. It’s widely applied for students, artists, athletes, inventors, games, or mobile terminal developers to develop heart rate-related interactive works. 

You can wear the sensor on your finger or earlobe and connect it to Arduino. It also has an open-source APP program that can display your heart rate in real-time in graphs. It’s in short, a heart rate sensor integrated with an optical amplifier and noise elimination circuit.
