Topic: Arduino Underwater Sonar/Altimeter (Read 71869 times) previous topic - next topic


Guys, do we have any news on that?
I am struggling to find any type of Sonar Sensor for underwater utilization.
And Chinese have tons of them for the fraction of the price but in the form of finalized devices


I'd also like an update on this topic. Can we start a new discussion so more people can see? Many of the options I've seen were fairly expensive in the 200-300$ range for transducer and converter.

I'm building an ROV project that requires an altimeter as well and I've found this sonar altimeter from Blue Robotics that has an Arduino library and examples. It's still in the $200-$300 range but looks like it will work.

Here's the sonar:

And here's the sonar Arduino tutorial:

I'm interested in other options as well if anybody finds something.
