Heart Rate Monitor -

Wearable monitors can help detect irregularities like Atrial Fibrillation (AFib) or tachycardia (a resting rate over 100 bpm).

For those interested in electronics, building a heart rate monitor is a popular beginner-to-intermediate project. Enthusiasts often use an Arduino paired with a pulse sensor to display live data on an LED screen or serial monitor. Some even utilize smartphone cameras and flashes as makeshift optical sensors to extract pulse data through Python processing.

Commonly found in smartwatches

and fitness trackers, these sensors use green LED lights to illuminate the blood vessels in your wrist. By measuring the changes in light absorption as blood pulses through, the device calculates your heart rate.

A heart rate monitor is a personal monitoring device that allows one to measure and track their heart rate in real time or for later study. Originally designed for medical use, these devices are now staple tools for athletes, fitness enthusiasts, and individuals tracking general health. How Heart Rate Monitors Work heart rate monitor
