Particle concentration sensing method and portable electronic apparatus applying the particle concentration sensing method
First Claim
1. 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 flowing into the portable electronic apparatus;
a second light source, configured to emit second light;
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;
wherein second scattered light is generated while the second light emitting particles in the air;
wherein a spectrum of the first light and a spectrum of the second light are different;
wherein the processor calculates a second particle concentration based on the motion and the second scattered light sensed by the light sensor, and calculates a third particle concentration based on the first particle concentration and the second particle concentration.

Abstract
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.
