Water quality monitor

I created this water monitoring device for the gravitational currents and the life magic exhibition at the Empty Gallery Hong Kong an exhibition of works by Susanne Winterling. It is a part of an artistic research project by Susanne that explores planetary sensing navigations below the surface. The device is based on a design by Shan He of Public Lab in cooperation with the folks at DF Robot.


The following part list is based on what was available in Berlin. The DF Robot parts were mail-ordered. The rest of the parts were procured locally from Condor, an electronics/hobby shop, and Bauhaus, a hardware store.
