Claim 12:
13. A system comprising:
a measuring device that acquires information relating to a fluctuation of power consumed by a fan motor of an electrical product operated around a user, the electrical product including a controller, a sensor and the fan motor, the controller controlling a rotation speed of the fan motor based on air quality of air detected by the sensor; and
a server that executes
communicating with the measuring device via a network,
obtaining the information relating to the fluctuation of the power from the measuring device,
determining a product consumed by the user and a consumed amount of the product based on the information relating to the fluctuation of the power, the fluctuation of the power correlating with the air quality around the user, the air quality correlating with the product consumed by the user and the consumed amount of the product,
calculating a remaining amount of the product based on the determined consumed amount of the product, and
ordering the product when the calculated remaining amount of the product is equal to or less than a threshold at which the product is ordered.
