MOBILE DEVICE BEING CAPABLE OF SENSING PARTICULATE MATTER AND PARTICULATE MATTER SENSING METHOD THEREOF

摘要

Disclosed is a mobile device, capable of measuring fine particles. The mobile device comprises: a housing prepared with an air flow path in which air flows, when the mobile device is shaken; an inertia sensor for detecting the acceleration of the mobile device; a light scattering-type sensor for detecting fine particles in air, which flows through the air flow path; and a control unit equipped with a counter for counting the fine particles detected by the light scattering-type sensor, and equipped with a flow rate calculation unit for detecting a flow rate of the air passed through the air flow path based on a detection signal of the inertia sensor. According to the present invention, the fine particles are measured based on a fine particle measuring structure without a fan, and thus the mobile device can be minimized.
