Water scarcity has become the most inexorable problem these days. In urban areas, most people live in flats, apartments where they need to get water from the corporation and then they ought to supply for each flat and apartments. Supplying water in normal ways consist of a greater number of technical problems and is difficult to access on a regular basis. In this project, we have built a working prototype to solve these problems. Our model contains two small mini-sub water tanks and one Main water tank. Each node (tank) can function automatically based on the tank and measuring groundwater levels or for other problems. And we will get real time information on smart phone via Bluetooth. In this project we will be using Arduino UNO as microcontroller. ©BEIESP.
