A bathroom automatic watering system using a light sensor is provided to save energy by connecting a motion sensor and a light. A bathroom automatic watering system using a light sensor is composed of a motion sensor(A) sensing the motion of a user, a light(B) installed over a washstand, and a light sensor(F) connecting the light and a center light of a bathroom. The light sensor measures the change of light. If a user comes to the front of a washstand to wash hands, water is discharged by sensing the shadow with the light sensor. |
