PLC  Based Automatic Pattern Generated Square Water Curtain Fountain

Comment errors or corrections found for this circuit, and get the chance to win big!

In this designed project, the flow of water will be in the form of a fountain with a special different pattern. When the project is switched on, the water pump motor will continuously feed water, various combinations of solenoid valves will be on and off as per the programming of the plc. From which we will see pattern based water fountain. In this project, we have used seven timers for different delays. We can keep their time period as per our own. In the ladder diagram shown here, we have set the time delay up to 1 second, 2 second, ….7 second. This time period taken in the project can be easily changed through programming.

Note: All Solenoid Valves are supplied via same Cooler Pump Motor

The solenoid valves are used to create the different pattern based waterfall, since they are connected to a programmable logic controller (PLC) which gives command/signal for them so that they will be open or close.

In smart pattern based square water curtain fountain much significant

Is placed on the accuracy of the waterfall, which permit the lucidity or Clarity of the water.

Smart pattern based square water curtain fountain is based on water movements in vertical direction with different pattern. Our proposed project is versatile and compare to ordinary fountain it require small space for its installation.
