A dust sensor according to the present invention comprises: a case comprising an air inlet through which air for the measurement of dust concentration is introduced; an air flow path for guiding the flow of air introduced into the case through the air inlet; and a light emitting device irradiating light toward the introduced air, wherein the air flow path includes a dust sensing unit in which the light irradiated from the light emitting device collides with the dust and scatters to measure the dust concentration, and the air flow path is divided into a front flow path and a rear flow path based on the dust sensing unit, respectively. A collecting unit for collecting the dust of a predetermined size or larger is disposed in the front flow path.
