At this month’s Consumer Electronics Show in Las Vegas, an overly “smart” showerhead called the Hydrao was shown. It basically detects how much water you’re wasting with those long showers.
Using sensors and LED lights, when it glows green, it mean less than 10 liters of water has passed through its base. The color changes to purple when you surpass that mark, and turns orange once you’ve used 30 liters. At the 50-litre mark, it blinks red – meaning, it’s time to get out of the shower!
