General Description
        The VC8201A is an ultra-low power Heart Rate sensor with an I2C/SPI interface. The PPG signal reflects the blood movement in vessel, which goes from the heart to the wrist or finger through the blood vessels in a wave-like motion. Therefore, We can use this PPG signal data to calculate HRM and HRV value.
        The VC8201 can be widely used in wearable devices, and provides a continuous hardware entrance for human health data.
