Pulse Sensor

Pulse Sensor, an open source hardware project by Joel Murphy and Yury Gitman, is a plug-and-play heart-rate sensor. It can be used to easily incorporate live heart-rate data into their projects. Pulse sensor consists if an integrated optical amplifying circuit and a noise eliminating circuit. Clip the Pulse Sensor to your earlobe or finger tip and plug it into your Arduino, you are ready to read your heart rate. The Pulse Sensor comes handy for students, artists, athletes, makers, and developers alike.
