How does the Peloton heart rate monitor function?

The Peloton heart rate monitor operates by employing optical heart rate technology to measure the user's pulsations via light. This device is typically worn around the arm or chest and includes sensors that emit LED lights which penetrate the skin without causing harm. As blood pulses through the veins, it causes variations in light absorption, which are detected by the monitor's sensors. The sensor's electronic component then interprets these variations to calculate the heart rate. The data acquired is wirelessly transmitted using Bluetooth or ANT+ connectivity to be displayed on compatible devices, such as a Peloton bike or treadmill screen, allowing users to track their heart rate in real-time during their workouts for optimized training and performance monitoring.
