Abstract

A first sensor may be configured to measure a sensed amount of a physiological parameter and to generate a first signal based on the sensed amount of the physiological parameter measured by the first sensor. A second sensor may be configured to measure a temperature and to generate a second signal based on the temperate measured by the second sensor. A housing may have heat-generating electronics including a processor that may be configured to determine an overall amount of the physiological parameter based on the first signal generated from the first sensor and the second signal generated from the second sensor. The second sensor may be thermally insulated from the heat-generating electronics.
