He wanted to do a little more with the equipment so he ditched the watch and built an Arduino-based heart rate monitor. He’s still using the chest strap and was happy to find that SparkFun sells ...

Heart-rate monitors, body-worn fitness trackers, and smart scales are just a few of the options to measure and monitor personal ... red (650 nm) and infrared (IR) light (940 nm).

Put your finger on the heart rate sensor in the base, and an Arduino Nano actuates a single servo to your own personal beat. We’d love to see it work overtime while someone gets worked up.

Here's a good one, showing you how to build a heart rate monitor using a Genuino 101 with Bluetooth comms. The project takes advantage of the Bluetooth Smart comms (aka Bluetooth Low-energy) built ...

The sleep monitor was developed using an Arduino Nano for their final ECE 4760 project and takes the form of a base station and glove which measures heart rate using an infrared sensor together ...

While at CES 2016, I got a sneak preview of the MAX30102 optical sensor. I met with Maxim Integrated and saw a really neat optical heart rate ... the 850-1000 nm wavelength light band. The pulse ...

You may be interested in a project published to the Hackster.io website earlier this year providing instructions on how to create a simple wearable heart rate monitor using an Arduino Nano R3.
