A mobile terminal capable of measuring dust, a dust data service system, and a method thereof are provided to generate scattered light pulses by irradiating light as heating the air, and to take a picture of the scattered light pulses as analyzing the taken picture, thereby extracting an amount of dust. An air heater(110) heats the air by being comprised at a predetermined position of a mobile terminal(100). A light source(130) is installed in the vicinity of the air heater(110), and irradiates light on the heated air to generate scattered light pulses. A camera(120) takes a picture of the scattered light pulses. A storage(150) stores image data taken with the camera(120) together with measurement time.
