The light source emits light of different wavelengths. The receiver generates one or more acoustic wave measurement values based on acoustic waves irradiated from the light source to air particles. The controller controls at least one flickering cycle of the light source, determines the type particles based on the acoustic wave measurement values, and calculates the concentration of particles. The controller calculates the concentration of particles in proportion to an intensity of the acoustic wave measurement values, and determine the type of particles based on the acoustic wave measurement values. The acoustic waves are generated differently based on wavelengths of light emitted from the multi-wavelength light source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dust sensor and electronic product using the same","description":"A dust sensor includes a multi-wavelength light source, a receiver, and a controller.
