Conserve water without compromising your hygiene with the Hydrao Smart Shower Head. With a typical 10-minute shower eating up nearly 50 gallons of water, a system to manage the flow and track the usage is necessary. Fitting securely onto any standard shower head fixing, this incredible device has built in LED lights to indicate how much water you’ve used while also restricting the flow. Using Bluetooth, you can set the app to alert you in intervals of your choice like 7 or 10 gallons of water. As if Hydrao couldn’t be any eco-friendlier, the device doesn’t actually use any electricity to work. Tucked neatly inside the shower head is a small turbine that uses the flow of the water to produce power.
