Hello all,
I am planning out a robotics project that I would eventually like to use outdoors; and I am looking for any practical advice on how to prevent moisture buildup inside electronics cases.
Normally, this sounds like a job for an ingress-protected box; but the real problem is humidity in ambient air. Under normal conditions, a simple sealed box would be sufficient. However it seems if the electronics inside the box are cycled on and off throughout the day, there is a change in internal air pressure that can draw moist air past any flaws in the seal, and into the box. If this cycle continues several times, condensation will form inside to ruin the components; and if you've ever seen auto headlamps with water trapped inside, this pretty much what I'm trying to avoid.
I've seen a few vendors selling vent plugs that allow air though while blocking moisture and particles. So basically, my questions are: has anyone here tried the vent plug technique? Are these generally worth trying out? Are there any techniques you recommend?
