The Airquality Graph is a little machine that measures the surrounding air quality and draws a circular graph over the period of a day (12hours).
I made this with and for Lana Schneider, student Fine Arts (drawing) at KASK.
It uses a figaro TGS2620 sensor with a high sensitivity to vapors of organic solvents and other volatile vapors. It also has sensitivity to a variety of combustible gases such as carbon monoxide, making it a good general purpose sensor.
The laser cutting was done at timelab.
