The drinking water emergency in India is arriving at disturbing extents. It may very soon achieve the idea of worldwide emergency. Consequently, it is critical to save water. In home established water tank, the one issue is exceptionally normal to us that the control of water level of overhead tank, therefore the wastage of water is expanding step by step. Be that as it may, we as a whole realize water is exceptionally valuable to us. This issue can be constrained by a basic electronic circuit comprises with some modest electronic segments, that circuit is called 'Water Level Indicator'. The activity of water level controller works upon the way that water conducts electricity. Along these lines, water can be utilized to open or close a circuit. As the water level ascents or falls, various circuits in the controller impart various signals. These signals are used to switch ON or switch OFF the motor pump as per our requirements. Water Level Indicator is a simple low-cost circuit. First, we introduced this circuit from the web. There the circuit is made with various components like transistors (BC547.BC548) Resistors, Led and etc. After we examined that how to make the circuit without transistors and after we figure that we got the outcome, close to we found support from our instructor about this circuit. Finally we got a basic circuit without transistor and it shows result. We removed the transistors to make the circuit cheap and easy installation to all. The other fluid control circuits, which we have seen those are very precarious than this circuit.
