After we did a lot of research, we found that we can help the people that live in coastal places to know the rising of water. Else we found that 101325 pascals of water pressure are equal atm of water. We will design an acrylic box with a hole Away from the beaches of coastal cities at least 20 kilometers, inside the box two batteries, Arduino, pressure sensor and WIFI module. The pressure sensor will be outside the box and communicated with it. Then we will cover the wires that communicated the box with sensor with insulated matter and cover the hole with wax.

The Arduino will be communicated with WIFI module. We wrote the code that consist if the pressure of water increased than 50662.5 pascals thus, the water level will be increased 5.165 meters height. This is very dangerous. So, by the WIFI module, the notification will be sent to the application.

Then people will be careful of any waves or rising water.
