Abstract: The present invention provides an asymmetric optical sensor device comprising: a light emitting unit for outputting light; a light receiving unit which receives the light reflected by an external object, and consists of a plurality of pixels which correspond to regions of different angles with respect to the light emitting unit and are arranged in a row; and a lens unit for diffusing the light from the light emitting unit. The light amounts received by the plurality of pixels are light amount values which are asymmetric with respect to the center of the light receiving unit.

Abstract: Disclosed herein are a dust measuring apparatus and a mobile terminal for controlling the same. The dust measuring apparatus includes a flow channel defining unit for defining a flow channel allowing a fluid containing dust to move through, a light emitter for emitting light into the flow channel, a light detector for detecting light scattered from the dust in the flow channel and converting the same into an electrical signal, and a controller for controlling the flow channel defining unit, the light emitter and the light detector. The controller is configured to verify whether a detection value received from the light detector is within an effective measurement range, vary the effective measurement range when the detection value is outside the effective measurement range, and measure, when the detection value is within the varied effective measurement range, a dust concentration based on the detection value.
