摘要
A portable electronic apparatus can sense particle concentration, comprising: a motion detector, configured to detect a motion of the portable electronic apparatus; a first light source, configured to emit first light, wherein first scattered light is generated while the first light emitting particles in air; a light sensor, configured to sense the first scattered light; and a processor, configured to calculate a first particle concentration based on the motion and the first scattered light sensed by the light sensor. Via such apparatus, the particle concentration can be calculated without a fan, and the accuracy for calculating particle concentration can be increased if more than one light source is employed.
