1. A method of determining an analyte level by compensating for ambient temperature using a single temperature sensor, the method comprising:
- receiving a sensor signal derived from an in vivo analyte sensor;
detecting a temperature measurement from a temperature sensor;
determining, with a processor, whether a threshold requirement is exceeded based on the temperature measurement; and
determining, with the processor, a temperature-compensated analyte sensor signal;
wherein when the threshold requirement is not exceeded, the temperature-compensated analyte sensor signal is determined using the temperature measurement; and
wherein when the threshold requirement is exceeded, the temperature-compensated analyte sensor signal is always determined using an ambient-compensated temperature that is derived by compensating the temperature measurement for ambient temperature.
