Electronic Water Level Controller Device

We all use water daily for various purposes but not many of us really care for the unnecessary wastage of water. There is water crisis in Asia, especially for drinking water, which is scaling to considerable peaks. This might very soon attain the nature of global crisis. Therefore, it is of utmost importance to preserve water. The filling of water tanks have been done through electrical pumps in the recent. However, untimely turning off the motor pumps lead to less filled tanks or over flown water from the tanks causing wastage. In order to avoid such situations we can have an electronic water level controller which can monitor the water level and switch the motor pump accordingly. This water-level controller circuit makes this system automatic. It switches on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre-determined level.
