Hello, I have a question about frequencies.
I am currently working on a project, in which I'm trying to detect incoming waves of the sea.
First thing comes to mind was to use the ultrasonic sensor, but would it be possible? Would it's 20kHz frequency detect Seawater, or should I use a different frequency.
If it's not possible to use the sensor, I might have to design a new sensor altogether, but I don't know at what frequency Seawater reflects the radiowaves.
Sorry if I made any mistake, first time posting in this forum.
