Visualising CO2 Emissions

An exhibition piece for Duncan Shingleton as a part of the Internet of Cars project, visualising live CO2 data that is otherwise invisible. Each tube represents an Automatic Numberplate Recognition (ANPR) camera on the A354 near the South coast of England. Using the car's number plate its make and model can be determined and from that the amount of CO2 it emits is estimated. The greater the CO2 produced at each of the cameras the more air is blown up the tube creating greater turbulence. LED lighting is used to colour the particles in line with the standard energy efficiency classes.

Each tube is powered by an Arduino Yún that pulls down JSON data from a server to control two blower fans and a NeoPixel LED ring. 3D printed components direct and focus the airflow.
