The design of the ring uses a standard thermal tape of thermal releases, without any calibration and amendments to the fact that the ring on the inside is heated by the surface of the skin of the finger (which is already below the body temperature) and outside-dissipates the temperature into the environment.

You want to measure the temperature in the room-take off the ring and leave for 10 minutes to lie down.
