The CYCPLUS H1 heart rate sensor is specifically designed for athletic activities where freedom of movement and real-time data are paramount. Thanks to innovative optical sensor technology, the sensor continuously measures your heart rate with an impressive accuracy of ±1 BPM. Its simple one-button operation and comfortable fit on the forearm or upper arm make it an ideal alternative to traditional chest straps. A standout feature is the visual display of heart rate zones through colored LED lights directly on the device: Green indicates ≤80 BPM, Orange represents 80–140 BPM, and Red signals ≥140 BPM. This allows you to instantly recognize your training status without having to look at a display. The connection via Bluetooth 5.1 and ANT+ ensures seamless compatibility with numerous devices – from sports watches to GPS bike computers and fitness apps. With a charging time of just 30 minutes and an impressive battery life of over 110 hours, the H1 is always ready for use, even during intense workouts. The magnetic charging function adds extra convenience. The heart rate sensor is IP67 waterproof, making it well-protected against rain and sweat – a reliable companion for all sports, indoors and outdoors.
