Best 3 Automatic Water Level Controller Circuit for Overhead Tank

Water is the essence of life and one should not waste it. There may have been many times where you would have wasted water when the overhead tank filled up with the excess water falling to the ground. Wouldn’t it be nice if we can prevent this wastage of water. This is exactly what the automatic water level controller does. You can control the water pumps with this simple circuit.

The automatic water level controller kicks in when the water in the overhead tank exceeds the required water level. It shuts down the water pump and prevents overflow of water thereby preventing wastage of water.
