Feature:
1The heart rate Bluetooth smart wristband adopt green LED lights (OSRAM lights) and sensitive photo-diode to monitor the flow of blood user' s wrist every single momentWhen user' s heart beats, there will be more blood run through user' s wrist, 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. SHH researching and developing team have effective monitored and extracted heart rate signal based on developed a set of complicated and explicit algorithm.
