Sensor Options Being Used

Curious what other sensors people are using with the Raspberry Pi/Pixhawk configuration… we have a temp and pressure… but we are looking to take our ROV out to dive shipwrecks… so what are people adding? Curiosity this Saturday night.

So far I’ve added a larger compass with GPS for logging initial surface position. I plan on adding a proximity sensor sonar next. I’d like to add a real sonar and an acoustic positioning transponder, but so far none of those exist in a diy inexpensive form.

Someday I might want to see if I can mount a metal detecting coil far enough from the ROV motors to actually be useful, but that might require the bigger rov, which needs bigger thrusters.

Which GPS unit are you using?

This one, but with a black case
