摘要： 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.

摘要： The present disclosure provides a photosensor structure including a left photosensor located at the left side of a front windshield of a vehicle viewed from the outside of the vehicle, and a right photosensor located symmetrically to the left photosensor. For example, the left photosensor includes two light reception windows located in a width direction of the vehicle to set a lateral incidence angle having a maximum incidence amount in a left-and-right direction of a light source, a dummy portion located on at least one of the two light reception windows between the two light reception windows to set an incidence altitude having a maximum incidence amount in an upward-and-downward direction of the light source, and light reception units located on lower ends of the light reception windows to measure the amount of light received from the light source through the light reception windows.
