Air treatment device with a detachable sensor module

1. An air treatment device, comprising:

an air treatment section operable to treat a first flow of air drawn from an ambient volume;

a controller configured to control the air treatment section;

a user interface configured to display, for selection by a user, at least one static or open-loop operational mode to be executed by the controller; and

a wall facing the ambient volume on a first side and comprising one or more pervious sections,

wherein a second side of the wall, which is opposite to said first side, comprises a connector for mating with a corresponding connector of a detachable sensor module;

wherein the connector, when the sensor module is present, enables a data connection from the sensor module to the controller;

wherein the user interface, when the data connection is enabled, is configured to display at least one closed-loop operational mode, in which the controller controls the air treatment section in response to measurement data relating to the ambient volume received from the sensor module; and

wherein the controller is configured to control the air treatment section with the at least one static or open-loop operational mode when the connector of the detachable sensor module is not connected to the connector of the second side of the wall.

2. The air treatment device according claim 1 , wherein the user interface, when the data connection is enabled, is further configured to display at least one indication of said measurement data relating to the ambient volume.

3. The air treatment device according to claim 1 , wherein the connector is positioned to allow the sensor module to cover an area of the wall coinciding at least partially with the pervious section(s).

4. The air treatment device according to claim 1 , further comprising attachment means for retaining and urging the sensor module onto the wall.

5. The air treatment device according to claim 1 , wherein the pervious section comprises three through holes arranged on the wall, at least two of which are located on different vertical levels.

6. The air treatment device according to claim 1 , wherein instructions for performing the at least one closed-loop operational mode are pre-stored by the controller.

7. The air treatment device according to claim 1 , wherein the user interface is configured to display the closed loop operational mode only when the sensor module is present and the data connection from the sensor module to the controller is enabled.
