Artist Victoria Button, and Southend Tech participants created an art project installation at the High Chelmer shopping centre in Chelmsford.
Live data from various council Smart City IoT pollution monitoring sites around Chelmsford was obtained via the internet. The Raspberry Pi uses that data to control DMX lights which project through four ‘leaves’ made out of squashed plastic bottles. The colours change from white light (no pollution) through to red light (lots of pollution).
There was a talk at the Chelmsford Raspberry Jam and Cambridge Raspberry Jam about the project.
Here is a video of Southend Tech and Victoria’s talk at the last Cambridge Raspberry Jam (photos are below) :
