An aerosol delivery device is provided. The aerosol delivery device comprises a control component and a humidity sensor. The humidity sensor is configured to measure a property thereof that is variable with relative humidity in an environment of the aerosol delivery device to which the humidity sensor is exposed. The humidity sensor is also configured to generate a corresponding signal that indicates a value of the property from which the relative humidity is calculable. The control component, or the humidity sensor, is configured to calculate the relative humidity from the value indicated by the corresponding signal, and control operation of at least one functional element of the aerosol delivery device based on the relative humidity so calculated, including output of the relative humidity for presentation by a display.
