Chest Strap HR Monitor

A Chest Strap HR Monitor is a fitness device that tracks your heart rate while you exercise. It is usually a soft elastic strap that wraps around your chest. The main part of the device is a small sensor that sits in the middle of the strap and rests against your skin. This sensor reads the electrical signals your heart sends each time it beats. This method is very accurate, just like the machines used in hospitals. The chest strap sends your heart rate data to a connected device, like a smartphone, fitness watch, or gym machine. Some models have Bluetooth or ANT+ for wireless connection.
