Title: PARTICULATE MATTER CONCENTRATION SENSOR AND MOBILE TERMINAL
Abstract:
A particulate matter concentration sensor and mobile terminal are provided. The particulate matter concentration sensor comprises a light emitting unit (11) and an optical processing unit (12) which comprises an optical electrical converter (122) and a filtering layer (121) provided on the optical electrical converter (122). The light emitting unit (11) emits the light with predetermined wavelength into the environment comprising particle matter. The scatter light is generated when the light with predetermined wavelength meets the particle matter and is scattered. The optical processing unit (12) is provided within the range of the scatter light. The scatter light, therein, is transmitted through the filtering layer (121),which filters the light except the scatter light,to the optical electrical converter (122). The optical electrical converter is used to convert the scatter light signal into the electric signal. The size of the particulate matter concentration sensor is greatly reduced by the mentioned structure.
