Save Water Project

Introduction: Save Water Project

The Save Water Project was created at the 1st SEMISH Hackathon at CSBC 2017

We created a little device to save water in a building with gamification. The Ideas was, that all occupants of the building measure their water usage and that they can compare on a dashboard how much they used in 1 comparison of the average of the house.

We used the Dragonboard 410 and the Grove Starter Kit for 96Boards.

The Project was created from:

  • Gabriel Magalhães
  • Lázaro Dias
  • Rodrigo Elias
  • Victor Marques
  • Clemens Putschli

You can find all project related files on our github repository:

    Keeping everyone conscientious of their water use is a great way to keep it lower :)
