SYSTEMS AND METHODS FOR SENSOR DRIFT COMPENSATION

摘要

An exemplary embodiment of the present invention provides systems and methods of compensating sensor drift. In one example embodiment, a system may comprise a primary sensor having a primary full-scale range and configured to output a primary environmental condition signal indicative of an environmental condition; a reference sensor having a reference full-scale range and configured to output a reference environmental condition signal indicative of the environmental condition, wherein the reference full-scale range is less than the primary full-scale range; and a drift compensation system configured to determine a drift compensation signal using the primary environmental signal and the reference environmental condition signal responsive to the reference environmental conditional signal being in the reference full-scale range and compensate the primary environmental condition signal using the drift compensation signal.

1. A system, comprising:
a primary sensor having a primary full-scale range and configured to output a primary environmental condition signal indicative of an environmental condition; a reference sensor having a reference full-scale range and configured to output a reference environmental condition signal indicative of the environmental condition, wherein the reference full-scale range is less than the primary full-scale range; and a drift compensation system configured to:
in response to the reference environmental conditional signal being in the reference full-scale range, determine a drift compensation signal using the primary environmental signal and the reference environmental condition signal; andcompensate the primary environmental condition signal using the drift compensation signal.
