Abstract
The present disclosure provides a proximity sensor including a light-emitting part that is configured to emit first light of a specific wavelength band, a light-receiving part that is configured to receive the first light and second light, the second light belonging to a different wavelength band from the first light, and a controller that is configured to recognize a proximate object based on the first light reflected by the proximate object, wherein the controller changes a light-reception range of the light-receiving part based on the second light.
