A wall mountable sensor module includes a housing defining an internal space that is segmented into a first internal space and a second internal space. The first internal space defines an air channel that extends from an air inlet to an air outlet. Two or more sensors are configured to be exposed to the air flow channel. A first sensor is configured to detect a first air parameter and a second sensor is configured to detect a second different air parameter, wherein the second sensor is situated downstream of the first sensor in the air flow channel. The sensor module includes a fan housed by the housing, the fan configured to cause an airflow to flow in through the air inlet, through the air flow channel thereby exposing each of the sensors to the airflow, and out through the air outlet.

A building control device includes a printed circuit board (PCB) assembly with a controller. A lighting assembly is operatively coupled to the PCB and is controlled by the controller. The lighting assembly includes a light guide that extends around a periphery of an interposing region. The light guide having a front face and one or more light sources optically coupled to the light guide such that light provided by the one or more light sources enters the light guide and is distributed to the front face of the light guide to provide a diffuse light output. A cover forms at least part of a front face of the building control device and includes a transparent region in registration with at least part of the front face of the light guide.
