    1. Is the heart rate/Blood Pressure/Blood Oxygen Monitor accurate? Why I measured an object can still get a value?

    It is the phenomenon that all smart watches will have. All measurements depend on sensors and algorithms and have certain errors. Smart watches measure heart rate mainly through photosensitive sensors, which receive light reflected from the arm skin and convert it into heart rate through algorithms.
