Toilets can appear to have flushed fully, but still have…material…stuck in the U-bend that hasn’t completely evacuated the toilet. A subsequent flush won’t work, even though the water in the bowl is clean.
Well, I suppose it is the kind of system where a lot of weird non-deterministic things can happen.
What kind of sensor are we thinking of here? Optical? I know it’s a real issue to find something that doesn’t foul or misread even in the simpler application of an RV septic tank.
I wonder if you could just put a window in the U-bend for manual inspection. It’s supposed to be full of “clean” water most of the time anyway.
Yeah, not to mention, adding any sort of electronic components to the thing would be dicey at best. A lot of bathrooms don’t even have power outlets anywhere near the toilet.
I’d prefer some sort of pressure-activated valve or something, but this is an engineering challenge that’s beyond my meager skills.

Ask me how I know.
