1. A system comprising:
- a housing that substantially defines an internal space;
an analyte measurement component that is within said housing or proximate said housing;
a first temperature sensor that is disposed at a first position within said housing and in thermal communication with a heat source;
a second temperature sensor that is disposed at a second position within said housing and in thermal communication with said heat source to a lesser extent relative to said first temperature sensor, such that ambient air contacts said second temperature sensor and displaces heated air proximate said second temperature sensor;
a first opening in said housing at a location proximate said second temperature sensor, a second opening at a second location in said housing, a channel extending between said first opening and said second opening and containing said second temperature sensor, wherein each of said openings place said channel in fluid communication with the ambient environment outside of said housing; and
,a processor that is disposed within said housing, is in electronic communication with said first temperature sensor and said second temperature sensor, and uses temperature data from said temperature sensors to calculate a temperature associated with said analyte measurement component.

Abstract
The present invention is directed to, inter alia, systems and methods for calculating a temperature associated with an analyte measurement component of a biosensing instrument (such as a blood glucose monitor), with a test strip that is inserted in a biosensing instrument, or both. The present systems and methods may employ at least two temperature sensors, and the acquired temperature information may be used to modulate data regarding an analyte in a biological sample, thereby providing a more accurate measurement of the analyte.
