GH3011 is an ultra-low-power and ultra-high-precision heart rate sensor that integrates three LED drivers, a photodiode (PD), and an analog front-end. It can monitor heart rate (HR), heart rate variability (HRV), and peripheral capillary oxygen saturation (SpO2) and enable wearing detection. GH3011 can be widely used in smart wearables such as wristbands and watches, professional sports gear, and fingertip oximeters.
