SYSTEMS AND METHODS FOR USING A PLURALITY OF SOLID ELECTROLYTE SENSORS FOR A SELECTIVE, LOW RESOLUTION FORMALDEHYDE DETECTOR

摘要

Systems and methods for determining the concentration of a second target gas while in the presence of a first target gas. A method may comprise operating a first sensor (202, 302) under a first operating condition, wherein the first sensor (202, 302) is part of a sensor assembly (200); operating a second sensor (204, 304) under a second operating condition, wherein the second sensor (204, 304) is part of the sensor assembly (200), and wherein the second operating condition is different from the first operating condition; detecting at least one target gas by the first sensor (202, 302); detecting at least one target gas by the second sensor (204, 304); processing a signal output from the first sensor (202, 302) with a signal output from the second sensor (204, 304); and determining a concentration of at least one of the first target gas and second target gas based on the processed output signals.
