The Hydrao Smart Shower ($99) is making a splash at this year’s Consumer Electronics Show in Las Vegas. The intelligent shower head uses a color LED system to let the user know how much water they are wasting.
Firstly, the user downloads an app that allows them to set specific parameters for water usage. It offers three alert thresholds and allows the user to track water consumption. A simpler, non-smartphone compatible version starts flashing red after about 13 gallons of water usage.
The product, developed by French company Start & Blue, can be attached to any standard shower fitting and a tiny turbine within the product generates enough energy to run the lights.
