Hello, everyone.

I'm thinking of building a simple water pressure sensor from simple easy-to-get everyday household materials. This 'water pressure sensor' should be quite simple and its concept easy to understand, easy to make but able to measure and show readings of water pressure up to 1 meter in depth. Does anyone know how to make one from scratch?

 

The simplest is a manometer. All you need is tubing and a board. Here's a reference to somebody who did it already:

Have a good time.

Flexible plastic tubing, like Tygon, taped to a meter stick.
