A water level indicator detects and indicates the level of water in an overhead tank and relays the information back to a control panel to indicate whether the tank has a high or low water level.
In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level indicator.
Using this circuit you can easily control the wastage of water and electricity.
Watch this video, for detailed step by step instructions on how to build this circuit and to know how this circuit works. Towards the end of the video I will also discuss whether its really worth building this circuit.
