광학 센서는 광을 발신하는 발광 소자; 발광 소자로부터 발신된 광을 수신하고, 수신된 광의 세기에 따라 전류를 출력하는 수광 소자; 발광 소자와 연결되고 온도에 따라 전기적 저항이 변화하는 온도 감지 소자; 및 발광 소자에 직접 전류를 공급하는 제1 채널과, 온도 감지 소자를 거쳐 발광 소자에 전류를 공급하는 제2 채널과, 수광 소자로부터 출력된 전류를 수신하는 제3 채널을 구비한 마이크로 컨트롤러를 포함할 수 있다.

    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.
