摘要： A method includes determining a difference in voltage value for a light emitting diode based on a first voltage at the light emitting diode for a first current and a second voltage at the light emitting diode for a second current and determining a temperature for the light emitting diode based on the difference in voltage value. The method further includes outputting an indication of the temperature.

摘要： A method for measuring oxygen saturation includes determining a difference in voltage value for a light emitting diode based on a first voltage at the light emitting diode for a first current and a second voltage at the light emitting diode for a second current and determining a temperature for the light emitting diode based on the difference in voltage value. The method further includes determining an intensity of a received photonic signal corresponding to an output photonic signal output using the light emitting diode and determining an oxygen saturation level based on the intensity of the received photonic signal and the temperature for the light emitting diode. The method further includes outputting an indication of the oxygen saturation level.
