Automatically controlled curtains that can rise and fall：

• Time control module：At a certain time of dawn or dusk, the curtains are required to automatically rise and fall according to the received time command;

• Photo sensitive control module: The light sensor receives light and converts the light signal into an electrical signal. The automatic rise and fall of the curtain is achieved by the light intensity;

• Interface module: Manual control of curtains by designing a web-based graphical user interface.

The Raspberry Pi 3, photosensor, motorized pulley system, PCB board and web graphics user interface form a complete curtain control system.

The following is a brief overview of how this real-time project works in the form of a system block diagram.
