Abstract
A portable apparatus for estimating air quality is provided. The portable apparatus includes a light source unit suitable for emitting incident light having a predetermined wavelength toward air to generate scattered light which is reflected by particles in the air, a light detection unit suitable for collecting information on the scattered light, and an arithmetic unit suitable for analyzing the information on the scattered light which is collected by the light detection unit. The arithmetic unit generates information on a size and a concentration of the particles in the air. Related methods are also provided.
