Internally his heart rate monitor is using an Arduino Pro Mini, a small OLED screen, and a turn-key pulse sensor which was originally conceived as a Kickstarter in 2011 by “World Famous ...

How fast does your heart beat? It’s a tough question to answer, because our heart rate changes all the time depending on what we’re doing and how our body is behaving. However, ...

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 ...

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.

Continuous monitoring of heart activity permits measurement of heart rate variability (HRV), a basic parameter of heart health and other diseases. This Design Idea is a new design of pulse oximetry ...

Around back is a built-in heart rate sensor, the Pulse's main draw and namesake. A tiny optical sensor sits between red and green LEDs, which emit light in controlled impulses.
