At only $35, it sounds like a great deal. According to the diagnostic help for the product, it produces between 0-5V depending on liquid level.

abarrow,
This seems like it'd be very simple, yet accurate, way to monitor a holding tank. Drop an esp32 nearby with wifi and then what? Connect red to 3.3v, black to GND and blue to whichever pin reads the differential and set up a program? That seems simple enough. I have to be missing something....
