Abstract: An air cleaning system having at least one dust sensor and a method for controlling the air cleaning system may improve accuracy of dust sensors through linkage control of the dust sensors, and may normally operate a faulty air cleaner using dust sensors of the remaining communicating air cleaners other than the faulty air cleaner even when any one of the dust sensors fails to operate. The air cleaning system may select a master dust sensor through linkage control of the dust sensors, and may operate the plurality of air cleaners only using sensor information of the master dust sensor. Therefore, the air cleaning system may stop operation of the remaining dust sensors other than the master dust sensor, may reduce measurement noise produced by the dust sensors and power consumption, and may increase a lifetime of the dust sensors.
