PCB, reflow, and conformal coating or some sort of enamel over the exposed conductors. Without coating, there is no hope of that holding up underwater.

Nup. Can't do it. Not even close. I think I had three wires attached at one point, but that's it. The slightest hand-shake, the tip brushes one of the other wires, and off it comes.

I'll be looking for some sort of prebuilt module.

There's a $12.50 breakout board for this sensor, if that packages OK for you and you're willing to eat the previous cost as a learning experience of sorts.

Sigh.

It doesn't look like I can submerge this. There are a number of other sensors, but they supply a voltage out, not ic2. The ADC on an analog read pin will not be accurate enough.

I tried using an A/D chip hooked up to a voltage out pressure sensor, but just too much noise.

Oh, hang on. STEVAL-MKI183V1 . A breakout board that exposes the 'pipe' of the sensor (which the adafruit does not do), so I might be able to mount it on the outside of the fermenter and connect it with a small hole in the barrel. A bit bigger than it needs to be ... an option might be to scrape the traces to expose them and solder to that. The rest of the board could be cut ... then again, I could just use as-is. I't not going to be *that* big. Put it in some heatshrink - maybe just get some of that food-safe silicone mould stuff and dip the whole thing, being careful to keep the sensor port clear.

This, this could be do-able.
