Claim 0:
1. A multi-gas sensing system comprising:
a sensing circuit comprising one or more sensing elements, each of the one or more sensing elements comprising a sensing material configured to detect at least one gas analyte;
a management circuit configured to excite the one or more sensing elements with an alternating current at one or more predetermined frequencies, the management circuit configured to measure one or more electrical responses of the one or more sensing elements responsive to exciting the one or more sensing elements with the alternating current at the one or more predetermined frequencies, the management circuit configured to determine one or more characteristics of the sensing circuit based on the one or more electrical responses of the one or more sensing elements, wherein the one or more characteristics of the sensing circuit comprises a temperature of the one or more sensing elements; and
one or more processors configured to receive the one or more electrical responses of the one or more sensing elements and the one or more characteristics of the sensing circuit, wherein the one or more processors are configured to determine a concentration of the at least one gas analyte based on the one or more electrical responses of the one or more sensing elements and the one or more characteristics of the sensing circuit.
