During this experiment, I tried also "normal" waterproof ultrasonic sound sensors for Arduino and they seem to work as well. Now I am testing different sensors and currently work on an RC boat with an Arduino / GPS / ultrasound sensor on board to collect data. You can check a video about testing the sensors on my Youtube: https://youtu.be/njDQKdZzGMI My idea is to have the RC Boat I can send out scouting unknown anchorages. Maybe I change the Arduino for an ESP32 so I can monitor the depth in real-time.
But when I am already collecting this data I would like to share it and make it available in the chart for everyone.
Thanks for the link, is your arduino code on github?
I've just been given a tronic df48 hand held fish finder to play with, if I can get depth data then everything else should be quite easy, I'll hopefully have a waterproof box with a Pi Zero 2 & arduino/esp somehow getting the data then creating waypoints with depth is a click away ?
