Being able to provide a 500 Hz sampling rate means our device can capture very fine details of the PPG signal. This capability comes from using both a high-quality PPG sensor that can measure changes at such a quick rate and a powerful chipset that can process the resulting data stream efficiently. This combination allows for a high-fidelity representation of the user’s heart rate over time, which can contribute to the superior accuracy and performance of our product compared to competitors that offer lower sampling rates.
