Abstract

See full text

The present disclosure provides an optical sensor having constant sensitivity regardless of changes in temperature. The optical sensor may include a light emitting device configured to emit light; a light receiving device configured to receive the light emitted from the light emitting device, and to output current based on an intensity of the light; a temperature sensor coupled with the light emitting device, and having electrical resistance varying with temperature; and a microcontroller including a first channel for supplying first current directly to the light emitting device, a second channel for supplying second current to the light emitting device via the temperature sensor, and a third channel for receiving the current output from the light receiving device.
