I', still bulding my OpenRov but I ve realised that in order to add some enviromental sensors I have two posibilities, which by the way I dont know if are factible.
The first one, is adding the sensors directly to the controller board making sure that it will remain watertight, which I dont know how to do or even if it is possible.
The other one is making a watertight compartment with another arduino and try to connect it to the beaglebone wireless (by bluetooth or another way, I dont if it possible underwater).
I would like to have your advice before choosing one of them. I ve already made sure that the sensors are arduino compatible and that they are fully submersible. You can have a look on them on this web:
Very thankfull, Javi
