ABSTRACT:
A method and an apparatus for sensing an illuminance and a temperature around a humidifier and controlling a humidifying operation is disclosed. An illuminance inside a room in which a humidifying operation is applied by the humidifier is sensed by an illuminance sensor. The humidifying operation of the humidifier is operated in a sleeping humidification mode when the sensed illuminance is lower than a reference illuminance. The humidifying operation of the humidifier is operated in a normal humidification mode when the sensed illuminance is higher than the reference illuminance. A temperature inside the room in which the humidifying operation is applied by the humidifier is sensed by a temperature sensor. The humidifier executes a heater humidification and an ultrasonic humidification when the sensed temperature is lower than a reference temperature. The humidifier stops the heater humidification and executes the ultrasonic humidification when the sensed temperature is higher than the reference temperature. Accordingly, the humidifier provides an agreeable humidification environment to the user whether the user is sleeping or is awake.
