Description: ·ID107 adopt green LED lights(OSRAM lights)and sensitive photo-diode monitor the flow of blood through user's wrist every single moment,When user's heart beats,there will be more blood run through user's weisr. The green light absorption will increase,Under the interval of heart beats,less blood run through user's wrist.Thus the green light absorption decrease.Do researching and developing team have eddection monitored and extracted heart rate signal based on developed a set of complicated and explicit algorithm. ·Do formula for maximum heart rate calculate:Below 50% of maximum heart rate,it will not defind as sport exercise.Up to 50%-69% of the maximum heart rate,defined as low-moderate sport fat burning zone,fit for exercise beginner.
