Hi…i am a new user here.As per my knowledge it is a good place to start with a field deployable project, how do you plan on environmentally protecting it, powering it , and then testing and updating it in the field?
Also you may want to discuss the depth range you want to measure. Unfortunately pressure sensors/depth readings can be temperature dependent – so from a teaching point of view its a good idea to teach measurement traceability. For using two absolute pressure sensors, Onset Hobo propose this scenario, but it doubles the error. A colleague who has used the approach has found burying the atmospheric reference sensor keeps it in a stable temperature environment.
