Water Fixture Usage with a Single Sensor

LargeUbiCompFrontIcon650x650.png

Overview

HydroSense is a pressure-based sensor that automatically determines water usage activity and flow down to the source (e.g., dishwasher, laundry, shower) from a single non-intrusive installation point.

We are currently working on visualizations of this data to reduce water waste in the home. If you are interested in this, please email jonfroehlich@gmail.com
