Calibration of an air quality sensor in a device

A method for calibrating an air quality senor of a device, the device comprising a housing delimiting a cavity having an internal volume, the air quality sensor being adapted to measure a concentration of at least one air compound present in the internal volume, and a movable member configured to be moved by an actuator between an open position and a closed position, the housing being alternatively in an open state in which the movable member is in the open position and air can enter into the cavity from the outside of the housing, and a closed state in which the movable member is in the closed position and no air can circulate between an outside area of the housing and an inside area of the housing,

• the method comprising:
• switching the housing from the open state to the closed state;
• waiting, while the air quality sensor consumes the air compound that is present in the internal volume, for the internal volume to no longer comprise the air compound or to comprise a concentration of the air compound that is below a predefined threshold;
• and
• calibrating the air quality sensor.

• the method comprising:
• moving the movable member from the closed position to the open position such that the housing is switched from the open state to the closed state;
• waiting a predetermined duration, while the air quality sensor consumed the air compound that is present in the internal volume, such that the internal volume comprises a concentration of the air compound below a predefined threshold;
• and
• calibrating the air quality sensor.
