Custom Water Level Expansion - PNY Edition

[Pny]

Experimenting with a custom water level expansion... First I had the idea of putting several sensors on one board but I changed my mind and miniturized the design instead... Sensor on one side and the other components on the other side. Would be nice if I manage to put the electronics directly on top of the PVC-pipe...

My custom water level expansion ("RA PNY Edition") on top of a 1 EUR coin...

Cool
Show us the end result when it is all mounted, ok?

...and inside a 20 mm (0.79 inch) PVC fitting.

Cool concept. The only thing is that it's nice to run airline hose to where water is versus wires.. But I love the concept of having everything in a PVC cap.

Very cool concept. Would love to see how it works out.

Got the circuits an hour ago... It's just a few (not to small) components on the board so I managed to solder the components with my old hobbyist tools at home...

Very Nice!!!
Just be careful not to splash water in there when you insert the tube into the water

I'm by far not an electrical component designer like you or Roberto, but would it help to squeeze a layer of silicone onto there when you are done with it and have it working.

Just as a protection against water.

The best possible solution would be an air stone with a rubber sleeve to make it a perfect fit against the plastic wall.
The sleeve would be soft enough to create a "seal" between two hard surfaces (The airstone and the plastic wall) and the air stone is porous enough to let air pass through to the sensor.

I plan to cover or glue something in front of the elektronics...
