摘要
An airborne matter measurement device according to the present embodiment comprises: a light source capable of irradiating light toward a filter; and a sensor capable of receiving light irradiated from the light source and transmitted through or reflected from the filter. According to the proposed embodiment, the airborne matter measurement device comprises a light source and an optical sensor installed around a filter, wherein light irradiated from the light source is transmitted through or reflected from the filter and then can be sensed by the optical sensor. Therefore, airborne matter accumulated on the filter can be easily measured.
