1. A wall mountable sensor module for monitoring two or more air parameters of a building for use in a building control system, the wall mountable sensor module comprising:
a housing including:
a front housing;
a back housing, wherein the back housing is configured to mate with the front housing to define an internal space of the housing;
the front housing and the back housing segmenting the internal space into a first internal space and a second internal space, wherein the first internal space and the second internal space are separated from one another by one or more internal walls;
the first internal space defining an air flow channel that extends from an air inlet in the housing to an air outlet of the housing;
two or more sensors housed by the housing, the two or more sensors are configured to be exposed to the air flow channel, a first one of the two or more sensors is configured to detect a first one of the two or more air parameters and a second one of the two or more sensors is configured to detect a second different one of the two or more air parameters, wherein the second one of the two or more sensors is situated downstream of the first one of the two or more sensors in the air flow channel; and
a fan housed by the housing, the fan configured to cause an airflow to flow in through the air inlet in the housing, through the air flow channel thereby exposing each of the two or more sensors to the airflow, and out through the air outlet of the housing.
