Proposed as WRE work for Power Electronics (PBL scheme) in 2010 and presented as Bachelor Thesis (BT) in july 2011
Goal of the work
Design of water temperature color LED based for a shower column. The color of the water indicates the temperature level. Red is hot, blue is cold and green is moderate (see figure).

The proposed system does not incorporate battery. An original current flow harvester has been designed in order to get energy from the water pressure.

Project incorporates turbine design, PCB design, microcontroller programming and sensor interface. Electrical, electronic and mechanical design of the system has been considered in the work.
