Final Project Proposal

Another Application idea for Interactive facade modular louvers physical model

a light sensor that tracks sun ray

a 3d printed or laser cut louver

arduino that is programmed to make the louver rotate according to the sun ray angle

hinges to allow the rotate of the louver

Technical Modules

1- Mode 1: Automatic mode

1. Construction Parts: laser cut Louvers

3D printed connection parts

2. Input:

• Sensing: LDR sensor (for tracking light) - temperature sensor

3. Action: the louver rotates independently with servo motor according to the sun light sensed and the indoor temperature to maximize shading and thermal comfort.

4. Brain: An Arduino board would act as the smart device's brain that processes the light sensor and send orders to sevo motor

5. Power Management: 9V adaptor

2- Mode 2 : Manual mode

• Construction Parts: laser cut Louvers

3D printed connection parts

• Input:

• User Input: switch to turn off automatic mode and a potentiometer to control each louver in case of automatic mode is off

• Brain: An Arduino board would act as the smart device's brain that processes the swiches and send orders to servo motor

• Power Management: 9V adaptor

3- Mode 3: Night mode (for privacy)

3. Construction Parts: laser cut Louvers

3D printed connection parts

4. Input:

• Sensing: Microwave sensor (for tracking motion)

6. Action: the louver closes independently with servo motor according to motion sensed to maximize privacy to the indoor space.

7. Brain: An Arduino board would act as the smart device's brain that processes the ultrasonic sensor and send orders to servo motor

8. Power Management: 9V adaptor

The kinetic louver for external facades rotates to reach maximum shading allover the day to achieve thermal comfort in spaces. this works when the light sensor tracks the sun light and according to light intensity the controller (arduino) gives a specific rotation angle for the servo motor to rotate and blind sun rays.
