Best way to prep your project for outdoors / weatherproofing ?

[TomWS]

Please do note as well I think I may have been mistaken on the cause of my original issue (see comment on hot glue being porous) and that the silicon conformal coating may be enough (and not as messy and needing multiple coats).

Ah, yes, I did miss this comment.  Thanks for following up.  Of course, this now begs the question as to what you're using for the silicone conformal coating.  I did notice that the NeverWet info on this particular product stated that it's not recommended for electronics or clothing but this may be related to the plastic housings of consumer 'electronics', not circuit boards themselves.

I have 2 soil sensors getting ready and I will try to see what the difference its between the silicon and the neverWet, I think I'm short a moteino though so this may take a couple of weeks to get the results...

I'm looking forward to your results!

Thanks again,
Tom

With regards to waterproofing electronics, this might interest you :

where they demonstrate these and others (see the links in the video description).

@GregMo, very cool!  Thanks for posting!

The next question, of course, is have you tried any of these on a Moteino? 

It seems as if the liquid CorrosionX would be the most useful (and least messy) if you can just dip your circuit board and connectors into a bath of this stuff. 

I'll be deploying some new Moisture sensors this spring, I'll be trying this out!

I haven't had the chance to use those products myself as access for certain products is a bit harder here in SA (though i see they have a local distributor). That being said, the guys over at Flight Test (the vid above) are pretty thorough, and the long range telemetry equipment they use is very similar the the Moteino's and the RFM69's. I would be weary of using the products on items such as humidity sensors and various such sensors, but on the batteries and moteino's, it should be fine.

Thanks again to ChemE for the idea, we'll see how long the coating works...

My pleasure!  I've gotten enough help from the EEs that hang here, glad the conversation drifted near my discipline and I could be the one helping out.

Did you get a chance to try this stuff?
