We will make explain,bpm is indicated heart rate and mmHg is indicated blood pressure We use a green light sensor, in principle, when the skin contact with the sensor on the bracelet will be issued a beam of green light to hit the skin and to check the blood flow through the hand. When the heart beat, if the blood flow increases,the absorption of green light will increase,but heartbeat interval will be reduced.
