MOBILE DEVICE WHICH SENSES PARTICULATE MATTER AND METHOD OF SENSING PARTICULATE MATTER WITH THE MOBILE DEVICE

摘要

A mobile device which senses particulate matter is provided. The mobile device includes a housing having an air flow path through which air flows when the mobile device is shaken; an inertia sensor that detects acceleration of the mobile device; a light-scattering type sensor that irradiates the air flow path with light and detects particulate matter in air flowing through the air flow path; and a controller that includes a counter for counting the particulate matter detected by the light-scattering type sensor, and a flow rate calculator for detecting an air flow rate of the air flow path based on a detection signal of the inertia sensor.

1. A mobile device which senses particulate matter, the mobile device comprising:
a housing configured to have an air flow path through which air flows in response to the mobile device being shaken; an inertia sensor configured to detect an acceleration of the mobile device; a light-scattering type sensor configured to irradiate the air flow path with light and detect particulate matter in air flowing through the air flow path; and a controller which comprises a counter configured to count the particulate matter detected by the light-scattering type sensor, and a flow rate calculator configured to detect an air flow rate of the air flow path based on a detection signal of the inertia sensor.
