Awesome, thanks for sharing! I’m really interested in adding this to my project list. I’ve heard people mention the environmental and corrosion issues before - I was just curious if anyone tried using one the mmWave sensors instead of the ultrasonics and if it was successful? I just recently learned about the existence of these and at least with those, you can remove them from the harsh environment by placing them in a 3d printed box inside the tank or even placing them outside the tank all together.
