Abstract
Methods, apparatuses, and systems for calculating a compensated reading of a gas sensing apparatus are provided. An example method includes causing a first supply of a working voltage to a sensing circuitry of the gas sensing apparatus, determining a first output of the sensing circuitry, causing a second supply of a stimulate voltage to the sensing circuitry, determining a second output of the sensing circuitry, and calculating a compensated reading of the gas sensing apparatus based at least in part on the first output and the second output.
