What could I use for a depth sensor in a SeaPerch ROV? Answered
I am in the process of building a SeaPerch ROV, and I want to add a few sensors with an Arduino. I have the other ones figured out, but I can't figure out what I could use for a depth sensor. I've thought about using a pressure sensor and calibrating it to give me a rough estimate of how deep it is, but I don't think that'll work too well. So if someone has some ideas for what I could do for this, that would be quite helpful. Thanks.
