Hi Hunters!

Today, I am going to introduce a well-designed plug-and-play heart-rate sensor that can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. It can easily clips onto a fingertip or earlobe. It’s a super small too, button-sized with holes, so it can be sewn into a garment as well.

Features

• It had to actually work and be “plug and play” into Arduino (or other microcontroller).
• It should be super small and easy to place (sew, glue, clip) into wearables, sports, arts, or gaming applications.
• It could be used as a teaching aid for instruction on working with sensors, data visualization, and bio-feedback.

If you’ve ever shined a flashlight through your finger tips and seen your heart-beat pulse (a thing most kids have done) you have a good handle on the theory of optical heart-rate pulse sensors.
