Methods, apparatuses, and systems for providing a position sensing component are disclosed herein. An example sensor assembly may comprise: a primary sensing device, a reference sensing device located in proximity to the primary sensing device; and a flue coupled with one of the primary sensing device and the reference sensing device to provide a pathway for a first gas in a first area to access the one of the primary sensing device and the reference sensing device. The one of the primary sensing device and the reference sensing device is coupled to the flue and is configured to determine a first concentration level of the first gas in the first area. The other of the primary sensing device and the reference sensing device is configured to determine a second concentration level of the first gas in a second area.
