Xiaomi Mi Band 5 and Amazfit Band 5 feature on list of fitness trackers that could soon be able to take your temperature

There had already been some rumors swirling around that Xiaomi and Amazfit (Huami) were planning on upgrading some of their wearable devices with the ability to take temperature. Clues had been found in the code for the Mi Fit app that pointed in this direction, and now it seems even more evidence has been discovered that practically confirms the body temperature update is incoming.

According to the source (AndroidTR) the wearables that are likely to end up with such a body temperature-taking ability will be the Xiaomi Mi Band 2, Mi Band 3, Mi Band 4, and Mi Band 5, of which Amazfit (Huami) was instrumental in the development process. Along with those Xiaomi-branded fitness trackers, the feature-packed Amazfit Band 5 will also apparently eventually offer this useful utility.

The latest detective work from AndroidTR has uncovered the details that the fitness tracker would provide to its user with this body temperature-related function in operation. Without the required hardware present to take temperature in the usual manner, the smart bands would have to rely on pulse measurement – illness and fever would cause a rise in heart rate, with Liebermeister’s rule stating that each 1 °C increase in body temperature corresponds to eight beats more per minute.

With a relevant firmware update, devices like the Xiaomi Mi Band 5 and Amazfit Band 5 could possibly record such rises in pulse rate and associate them with the onset of fever or sickness, which considering the current COVID-19 climate would be a very useful signpost for the wearer at least, even if the data-recording method is not to a medical-grade standard.
