Joel Murphy and Yury Gitman of pulsesensor.com are developing an Arduino compatible pulse sensor.
“Pulse Sensor” is a well-designed plug-and-play heart-rate sensor for Arduino.
It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.
After a few months of testing a gaggle of techniques, we developed what we think is an innovative pulse sensor. Our prototype (and accompanying code) plugs right into Arduino and easily clips onto a fingertip or earlobe. It’s super small too, button-sized with holes, so can be sewn into a garment as well. We’d like to manufacturer the actual pulse sensor, making it low-cost, and accessible for students, artists, and developers to use in their projects.
