A system and a method for gas sensing while correcting for a poison level of a gas sensor. The gas sensor provides first dielectric excitation of the gas sensing material at a first set of frequencies, measures responses of the gas sensing material to the first dielectric excitation while the gas sensing material is in contact with the fluid sample, provides second dielectric excitation of the gas sensing material at a second set of frequencies, measures responses of the gas sensing material to the second dielectric excitation while the gas sensing material is in contact with the fluid sample, and determines, based on the responses of the gas sensing material to the first and second dielectric excitation, identities, respective concentrations, or a combination thereof, of at least one analyte gas in a fluid sample, and a sensor poison level of the gas sensing material.

System and method for gas sensor that corrects for sensor poison level

A system and a method for multi-gas sensing using dielectric excitation of a single sensing material operated at a single operating temperature. Contrary to conventional gas sensor designs, embodiments of the gas sensors disclosed herein implement a metal oxide semiconductor sensing material maintained at a constant temperature, wherein dielectric excitation responses of the sensing material are measured at this constant temperature while the sensing material is exposed to a fluid sample. The disclosed gas sensors and gas sensing methods unexpectedly provide desirable characteristics, such as enhanced multi-gas differentiation, while operating at the constant operating temperature. For example, by measuring dielectric excitation responses of using at least one gas sensing element at a single operating temperature, the disclosed gas sensors and gas sensing methods demonstrate superior multi-gas differentiation compared to other gas sensors and other gas sensing methods that rely on multiple resistance measurements performed at several different operating temperatures.

Gas sensors are disclosed having an on-board, low-power data processor that uses multivariable gas classification and/or gas quantitation models to perform on-board data processing to resolve two or more gases in a fluid sample. To reduce computational complexity, the gas sensor utilizes low-power-consumption multivariable data analysis algorithms, inputs from available on-board sensors of ambient conditions, inputs representing contextual data, and/or excitation responses of a gas sensing material to select suitable gas classification and/or gas quantitation models. The data processor can then utilize these gas classification and quantitation models, in combination with measured dielectric responses of a gas sensing material of the gas sensor, to determine classifications and/or concentrations of two or more gases in a fluid sample, while consuming substantially less power than would be consumed if a global comprehensive model were used instead. Thus, the data processor is utilized for linear, nonlinear, and non-monotonic multivariate regressions.
