The idea is to used the design module which created in G2- Bio tech morphogenesis studio and make a adaptive shading structure using Programming & Physical Computing.
Concept
The Innovative algae panels integrated into structures enrich the surrounding air with oxygen through photosynthesis. Complementing this, kinetic shading devices dynamically adjust based on sunlight levels, efficiently curbing the urban heat island effect. This combined system not only enhances oxygen production but also optimizes shading for a sustainable and comfortable urban environment, showcasing a holistic approach to environmental design.
Process
Temperature:- Temperature measurements are taken using a DHT11 sensor, based on the temp the shading panel will open and close.
Air Quality:- Use of an Air Quality sensor to calculate the air quality and this helps to show the amount of air pure by the algae panels.
Sun Light:- Use of an LDR sensor to detect the amount of sunlight based on the amount of sun rays shading the device open and close. I.e.;- in the evening and in the morning shade is open but in afternoon its automatically close based on intensity of light.
Movement:- Use a Stepper motor to rotate the panels to close the shading device. It depends on the DHT11 and LDR sensor.
