I did this with capacitive foil sensors on the outside of my plastic holding tank and uses and ESP32 with SensESP to send info over wifi to Openplotter. Worked great. Sold the boat though and I don't know where my code is, but there should be a reference thread on here about it. Might have even posted the code. SensESP made it easy, as I am not much of a programmer, but was able to figure it out.
