Identification of primary factors responsible for indoor environments gas sensor responses is difficult due to the residual components in the room. By removing these components from observed sensor signal, we analyzed the linear components of the gas transfer route. A gas transfer routes, generally expressed by Navier Stokes equation, are non-linear fields. However, gas transfer routes can be approximated to a linear field with reducing flow velocity. We report here a model of indoor flow field generated using a linear system, and applied this model to experimental results. The results of this study indicated that over 90% of residual components of the gas sensor response were linear. Thus, the identification can be improved by reducing residual components from the sensor response using the minimum phase inverse filter.
