Wasting water is not wise, but many of us do it unintentionally. Smart devices such as PowerShower can help you save water without making big changes to your lifestyle. PowerShower has a microprocessor and motion sensor to provide you with water when you need it. The device knows when you are under the shower spray and when you have stepped away.
PowerShower attaches to your shower head conveniently and could cut your water usage significantly. The product is expected to become available in June 2016.
