While Bluetooth heart rate monitors can meet the needs of most people—pairing the monitor with a smartwatch, say—ANT+ allows you to connect the heart monitor to multiple devices at once.

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.

Optical heart-rate monitors are the most common pulse sensors in wearables. Most of them glean heart-rate data through "photoplethysmography" (PPG), or the process of using light to measure blood ...

Today's heart-rate monitors can do more than measure a pulse. They also can tally the amount and rate of exercise, as well as the effort expended. They just need additional signal ...
