Polar H10 is a state-of-the-art classical heart rate measurement sensor comprising a chest strap and a transmitter unit. Polar H10 is designed to be used by top athletes, thus tolerating harsh conditions, such as sweat, electric disturbances and motion artefacts.
It is equipped with built-in memory and can be used online as a conventional heart rate sensor for heart rate and RR intervals with standard Bluetooth Low Energy connectivity. Furthermore, an SDK (Software Development Kit) is provided to enable access to online raw sample data, such as ECG and 3D acceleration. An example data logger application is available for Android to show you the principles of an application that you can create yourself.
