An internal heat-generating component noise correction technique can be used to improve accuracy of temperature sensing. In some examples, a method includes at an electronic device including a first temperature sensor and a first heat-generating component, measuring a first temperature using the first temperature sensor, and in accordance with a determination that one or more criteria are satisfied, compensating the first temperature based on a first estimate of heat generated by the first heat-generating component to generate a second temperature, and estimating a third temperature external to the electronic device using the second temperature.

Internal heat-generating component noise correction techniques for temperature sensor systems

Embodiments described herein are directed to a temperature measurement device that includes a sensor body configured to be placed on a skin of a user. The temperature measurement device can include a first section defining a first lower surface and having a first thickness, a second section defining a second lower surface and having a second thickness, and a channel separating the first lower surface from the second lower surface. The temperature measurement device can also include a first set of temperature sensors positioned across the first thickness, a second set of temperature sensors positioned across the second thickness, and a processor configured to estimate a tissue temperature of the user based on comparing temperature signals from the first set of temperature sensors with temperature signals from the second set of temperature sensors.
