Sustaining water resource is one of the major issues surfacing recently due to uncontrolled wastage of available fresh water. Majority of the water wastage takes place because of overflowing water tanks. In most of the cases, water tanks are manually controlled by an operator. In absence of the person, water keeps on overflowing until the motor is switched off. In some other projects, which are automated, dip sensors are implemented. As a result of being in contact with water, there is a high probability of rusting of material used in sensor. These projects can only control the water level locally, i.e. the operator is required to keep an eye on proper functioning.
Smart water tank implements non contact method using ultrasonic sensor. It can measure tank water level of maximum 13 feet height. IoT with the help of which the user can directly monitor water level in tank and control the motor on / off action through the smartphone and from any place in this world. The android application is developed to monitor water level. This project can be installed in existing water tanks.
