The water monitor project with JJ Obrien, another REAR Lab member, was an exercise in programming, circuitry and enclosure design. The original model was large and rectangular with a touchscreen and antenna for cellular connectivity. The enclosure was machined from aluminum and shown at an international conference in late 2019.

The final model was slimmed down by selecting a smaller board (Particle's Photon board) with cellular capabilities. Everything was placed on a custom PCB and fitted into an off-the-shelf enclosure with silk-screened diagrams and labels.
