Heart rate monitors with built-in heart rate sensor

Built-in

— internal sensors are integral to the heart rate monitor, distinct from finger sensors. Typically in constant contact with the body, these modules provide continuous pulse monitoring, eliminating the need for external devices that may be misplaced. However, stringent requirements for weight, dimensions, and fastening methods influence the price and can result in lower measurement accuracy compared to other sensor types. Consequently, models featuring these sensors are limited.
