Yury Gitman and Joel Murphy have created a pulse 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.
It also includes software for graphing BPM on screen. Included software also makes it easy to export live BPM data feed to software (or web app) of choice.
We caught up with Yury and Joel at the recent World Maker Faire community meeting at Etsy (video). They’ve started a Kickstarter page to help them launch the pulse sensor as an open source hardware kit.
