Hi i'm totally new to this forum and also so new to arduino tech.
The idea i had was to create my own data collection buoy, something really simple (at least in the beginning). I would like to take measurements of the free surface oscillation on the field (on the water surface), with some kind of a micro-controller and data logger system.
Is it possible to obtain the free surface variations using arduino hardware?
Who do I interpret the reading of an accelerometer?, cuz wave height is in meters!
Is it possible to create an autonomous device, that last at least for 3 months taking data each hour?
About the noise you were talking about i'm not quite sure what is it, but i'm sure you can clear it up for me .
The battery part if there is a way to only start the device each 30 min and take a measure and then shut it down again, i'm sure i'll have no problem on finding a proper battery that will last 3 months ...
