Loops and receive reflection loops, but the signal is extremely weak and very susceptible to external interference, resulting in inaccurate measurement data, and generally need to be measured in a quiet state. However, Xiaomi uses the principle of red light for cost considerations. In general, the price of 99 yuan to buy such a multi-functional bracelet is already very good.
