More Information
Summary:A dust sensor includes a light scattering area, a light emitting element for providing first light to the light scattering area, a light receiving element for sensing second light generated in the light scattering area, an air inlet connected to the light scattering area, and a heater provided in the air inlet. According to the present invention, accuracy and reliability of measurement in the dust sensor can be improved. 먼지 센서는 광 산란 영역, 광 산란 영역에 제1 광을 제공하는 발광 요소, 광 산란 영역에서 생성된 제2 광을 감지하는 수광 요소, 광 산란 영역과 연결되는 공기 유입로, 및 공기 유입로 내에 제공되는 히터를 포함한다.
