Water saving Smart Shower

Smart showerhead called the Hydrao, basically detects how much water you’re wasting with those long showers. Using sensors and LED lights, when it glows green, it means less than 10 litres 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 litres. At the 50-litre mark, it blinks red – meaning, it’s time to get out of the shower. http://www.enstarz.com/articles/135514/20160116/high-tech-showerhead-lets-you-know-when-youre-wasting-too-much-water.htm
