Still nothing. I did get a voltage increase on the signal wire, it jumped to .1 volts. Any ideas as to what could be wrong?

The GND only appears on the output side. Could you share a drawing of how I should wire this in?Looks like it’s still wired on the output side as well.
In order to bypass the converter board you need two resistors: one to limit current and one as a pull-up.

Any reason why this sensor wouldn't work?

That sensor should work just fine.
No I'm using a wykat board that has the circuit built into the board. You still need to use the board for that sensor. Not familiar with the pico boards cicuit layout but the dfrobot board you have should work for that sensor and then connect to the pico board.It does not come with that small board that the DFRobot sensor comes with. Are you using a pico board?

The circuit for wykats hat uses a 100nf capacitor, a 4.7k and 360k resistor. If the circuit for the pico board was made to use a mechanical float switch than the DFRobot board needs to be in there too. You just need to double check that the wiring from the board matches the pico board connectors. I will defer to @theatrus for confirmation of this since I'm not familiar with his boards layout.
You'll need that small breakout board for these optical (photo electric) sensors. These are required for pico base board (theatrus) as well. The pico based board can use float sensors directly.
Is there a newer temp sensor that is Recommended now?

Are they sealing it first?Also, some people have been reporting good results with this temp sensor too.

You know, I really do not know if they are being sealed. However, regardless of what others are doing, I would put a coat of silicone on them just for peace of mind.
Silicone does not have a good track record thus far. Maybe some plasti-dip.
I am not sealing mine for waterproof of the sensor, I have 2 of these and 2 more on the way, they are double crimped onto heavy silicone insulated wire...ones I have do not stick to a magnet...which is good enough stainless for a FW tank. YMMV in salt.You know, I really do not know if they are being sealed. However, regardless of what others are doing, I would put a coat of silicone on them just for peace of mind.
