What is the sensor indicator at the bottom of the Xiaomi Smart Band 9? And why is the red light blinking when the band is not worn at night?
If the red light and infrared light (not visible to the naked eye) turn on, it indicates that the band is measuring blood oxygen. If the green light is blinking, it indicates that the band is measuring heart rate.
If the band is not worn at night but the red light is blinking, please check the following methods:
1. If the advanced monitoring function is turned on, the band will automatically measure the blood oxygen after you fall asleep, and the red light of the band will blink. If you are not wearing the band but the red light is blinking, the monitoring function is misdiagnosed. The Xiaomi Smart Band 9 adopts a high-precision PPG heart rate sensor with infrared light, green light, and red light, which greatly improves its monitoring accuracy compared with traditional monitoring. However, when the band is placed in an environment that is more similar to the wrist, the monitoring function will also be misdiagnosed;
2. When the band is not worn, please pay attention to the heart rate light is not covered by objects (common misdetection scenarios: the band is placed in the bag, bed, table, etc.);
3. If you don't wear the band while sleeping, we suggest you turn off the advanced monitoring function, which can greatly save the power of the band.
