Hi Mohammad,

There are different kind of water sensors, some using metal probes, sensing capacitance between probes, some using ir sensing. 

You can find one or two circuits under the section

EG LABS > ELECTRONIC CIRCUITS

 

There are seven segment driver ICs available and there are also sample projects explaining how to use them in the same section.

 

Please refer them and feel free to post your further queries
