More Information
Summary:There is provided a smoke detector including a substrate, a light source and a light sensor. The light source and the light sensor are arranged adjacently on the substrate. The substrate is arranged with an asymmetric structure to cause an illumination region of the light source to deviate toward the light sensor thereby increasing a ratio of light intensity reflected by smoke with respect to reference light intensity.
