Been rving for 40+ years & have never had one that those sensors were more than little red lights signifying nothing.
You can try ice, magic potions, various elixirs, spend time & $$ so that they may work til the tank fills the next time.
Your shower will back up, usually about the time you're all lathered up, when that grey tank gets full. The galley tank typically last til the other tanks need dumped. The toilet has a distinctive burp/gurgle when flushed indicating it's nearing full. Learn these signs & forget looking at the sensors.
