PPG 500hz raw data wave

Support for RAW Data

Providing raw data offers flexibility and control to customers, allowing them to leverage their expertise and create value-added services or applications that are built on top of the foundational data that your smartwatch provides.

And being able to output synchronized raw data from gyroscopes and accelerometers is a unique selling point that can cater to customers looking for advanced motion tracking and analytics capabilities, and it showcases the high quality and versatility of our smartwatch platform.

Exclusive Access to Raw Sensor Data

Accurate PPG, Support Max 500HZ Sampling Rate

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.
