A digital nose detecting air pollution and dust particles

After Anywhere, Turbo-gusli and Solaris, Dmitry Morozov shared with us Digioxide, a new interactive work using Arduino Nano, hc-06 bluetooth module, gas and dust sensors, LG mobile printer :

This project aims to raise public awareness of the environmental pollution by artistic means.
Digioxide is a portable wireless device equipped with sensors of air pollution gases and dust particles that is connected to computer via bluetooth. This allows a person with digioxide to freely move around a city, seek out ecologically problematic places and turn their data into digital artworks.

The information about the concentration of dust and harmful gases, such as CO, CO2, HCHO, CH4 and C3H8 and spme others is algorithmically transformed into generative graphics, forming an abstract image. The device’s mobile printer allows instant printing of this air “snapshot” that can be left as an evidence on the place, or given as a present to a passerby.
