Huawei has officially launched the S-TAG professional motion sensor in China. The S-TAG was originally announced for the global market in May this year. Unlike the Apple AirTag, the Huawei S-Tag is designed for specific sports scenarios and can detect sports data when connected to smart devices such as smartwatches or smartphones. The tag supports professional running posture monitoring and scientific running posture analysis. 
The product is the brand’s first professional motion sensor. It comes with built-in 9-axis sensors, which can read the movements of the user’s legs and waist, analyze 13 parameters, and achieve monitoring of the user’s running movements. The product sees Huawei collaborating with the Chinese Academy of Sports Science to gather research data that is then used to proffer professional exercise recommendations.
The Huawei S-Tag features an ultra-lightweight build, weighing just 7.5g which is even lighter than a pair of TWS earphones. It has a clip that can be used to attach the product to the shoes or other points and the user won’t experience any form of fatigue even when it is worn for a long time. The device can also be submerged in up to 50 meters of water.
In addition to running, the Huawei S-TAG professional motion sensor also supports installation on the spokes of bicycle tires to monitor the rider’s pace, touchdown time, and other data to help riders improve their professional abilities.
The Huawei S-Tag is equipped with a 9-axis sensor that can control running techniques by reading the movements of the user’s feet and waist. The sensor will analyze 13 parameters to help achieve the perfect running technique. By collecting data during exercise, the device provides users with professional advice based on joint research by Huawei and the Chinese Academy of Sports Sciences.
In terms of battery life, when deployed as a steps counter, the S-Tag can guarantee a battery life of 30 days on a single charge. However, if it is attached to a bike during cycling, it can only guarantee just 36 hours of battery life. It has support for fast charging. The device also comes with waterproof features and can withstand water up to a depth of 50m.
The product carries a price tag of 299 yuan (~$44) for the standard model while the elite model is priced at 499 yuan (~$74). Huawei is still yet to announce the global availability and pricing details of the S-Tag smart sensor
