I have been working on a project, where It would be nice to measure the depth of water, from 10 cm depth to around 10 meters at max. With a resolution of +- 1-2 cm.
I am currently using a development kit from Arduino and a pressure sensor. And in the future i think it will be beneficial to measure salt in the water, to know the density of it and by that be able to calculate the actual Depth (height) of the water.
Do you think you can help me with this project?
If you do, leave a message, where you describe how you think you will be doing it and a realistic bid.
