Pulse sensor Arduino is used to test the heart rate sensor, students, artists, athletes, creator, game developer, or mobile terminal can develop interactive work related to heart rate. Sensor can be put on the finger or earlobe, through interconnected line and can be connected to the Arduino. It also has an open source app, can monitor real time of the heart rate and can display graph. It is a integrated optical amplifying circuit and noise eliminating circuit heart rate sensor.
