Abstract
A sensor calibration system includes a gas sensor configured to measure a thermal conductivity of a target gas. The gas sensor includes a reference chamber containing a reference gas, a measurement chamber containing a measurement gas, and a calibration circuit. The reference gas has a first thermal conductivity profile and the measurement gas has a, different, second thermal conductivity profile that are dependent on a first environmental stimulus and a second environmental stimulus. The calibration circuit is configured to, while the first environmental stimulus is varied and the second environmental stimulus is fixed, acquire a plurality of measurements. Each measurement of the plurality of measurements is representative of a difference in thermal conductivity between thermal conductivities of the reference gas and the measurement gas. The calibration circuit is configured to determine a target gas sensitivity of the gas sensor to the target gas based on the plurality of measurements.
