Hi,
I want to make something to measure swell and tides. Im messing with Raspberry pi 3 and have other sensors working but not sure how to do this one.
The tides mainly go from .0.3m to 4.5m and swell -2m > +2m
I was thinking of a floating sealed ball with an altimeter inside and also temp probe out the bottom a little.
After reading up how altimeters work is on pressure but if its inside a sealed ball would it not work properly, even when it gets warm and may increase the ball pressure a bit.
Am i thinking correct and if so what can it do or anything else i can try?
thanks for your help.
