GH3030

GH3030 is a health sensor that integrates multichannel PPG sensing circuits, capable of monitoring health indicators like as heart rate (HR), heart rate variability (HRV) and peripheral capillary oxygen saturation (SpO2). It has a distinct feature of ultra-low power consumption and extremely high precision, and is applicable to the smart devices like high-end smart watches and wristbands.
