This paper presents a method in reducing wasted energy within buildings and homes using blinds that utilize natural, ambient light from the sun. Rather than having unnecessary light from a light source, the automated light sensing smart blinds sense the amount of light outside the window and in the room, and accordingly adjust the angle of the blinds to save energy by utilizing the available outdoor light. This way, the light source will not be operating at maximum output power while there is excess light coming through the window. Hardware implementation and test results of the smart blinds demonstrate the capability to measure ambient light inside the room and outside the window, and then properly adjust the angle of each of the blinds on the window, thus automatically changing the desired brightness of the room. © 2018 IEEE.
