<p>PURPOSE: An air quality sensing and a power-saving method of a controlling network are provided to reduce power consumption by compensating the error of a sensing value in a preheat period. CONSTITUTION: An air ventilation system comprises a ventilation unit(150), a sensor(110), and a control unit(130). The sensor measures the concentration of foreign materials in the air. The control unit controls the sensor and the ventilation unit based on the measured information from the sensor. The control unit controls the sensing state of the sensor. In a preheat period, the control unit controls the driving of the ventilation unit based on a compensation value calculated by the measured information. The control unit applies the compensation value to a value measured by the sensor. [Reference numerals] (110) Sensor; (130) Controlling unit; (150) Ventilation unit</p> |
