The health tracker comes with an array of features, including a real-time heart rate sensor, SpO2, sleep monitoring, and more. Heart-rate sensors and sleep monitoring sensors are still understandable for many of us, but do you know what a SpO2 sensor is and how it works? If not, then you are at the right place. In this article, we have explained almost everything about the sensor. Keep reading to know more about the SpO2 sensor.
What is SpO2?
In simple words, the SpO2 sensor is capable of measuring your blood oxygen level. The human body needs oxygen to survive, which means that higher SpO2 levels are good for us. If you have lower levels of SpO2 means, you have symptoms of Hypoxemia. According to the reports, 95%-99% is a normal reading for SpO2.
How does the OnePlus Watch Measures SpO2 levels?
Fitness trackers like the OnePlus Watch are capable of measuring SpO2 levels in a similar way to how a heart-rate monitor works. The device uses a highly sensitive photodetector that is capable of seeing the haemoglobin in the user’s blood vessels. Smartwatches like the OnePlus Watch uses the reflectance pulse oximetry technique to measure SpO2 levels.
