Abstract
A method of calibrating a gas sensor comprises determining a sensitivity of a gas sensor to one or more conditions proximate the gas sensor, determining one or more initial calibration factors comprising a sensitivity of the gas sensor to one or more analytes of interest, determining a current sensitivity of the gas sensor to the one or more conditions proximate the gas sensor by measuring a response of the gas sensor while the one or more conditions proximate the gas sensor varies during operation of the gas sensor, and adjusting the one or more initial calibration factors of the gas sensor based, at least in part on the current sensitivity of the gas sensor to the one or more conditions proximate the gas sensor, and a relationship between the sensitivity of the gas sensor to the one or more analytes of interest to the sensitivity of the gas sensor to the one or more conditions proximate the gas sensor. Related gas detectors, related methods of compensating and calibrating the gas sensors, and methods of determining a functionality of the gas sensors are disclosed.
