Of course, there are various combinations. According to the market survey of various products, which is more accurate?

At present, photoelectric transmission measurement is the most common measurement method in the market. The sensor that contacts the watch with the skin will send out a beam of light to hit the skin to measure the reflected / transmitted light. Because the blood can absorb the light of a specific wavelength, every time the heart pumps blood, the wavelength will be absorbed a lot, so that the heartbeat can be determined.
