Moisture penetrates my outdoor enclosures...
-
Hi there! I have a few moisture safe enclosures for outdoor sensor. At least, that's what I thought but inspecting one of them today due to failure (see attached image below) made me aware that they are not moisture safe at all. They even seem to suck moisture from the outside and store it inside the box.
I guess that the plastic that the box is made of isn't moisture proof.
If some of you guys have experience to share with me on this topic I'd appreciate it a lot. I'd like to rebuild this repeater node using an enclosure that does not allow moisture to enter it and eventually destroy the electronics. Stability of operation and an enclosure that resists the environmental challenges that it will face has a much higher priority than the cost of the enclosure.
Cheers!
@รอเร-อ I've used Gewiss modular light switch boxes for years and no problems experienced - Winters go down to -20 and summer up to 45, and no appearance of condensation.

The front section has a clear flexible plastic window which hinges at the top, the front and main box are separated by a gasket, by undoing 4 screws.
I separate the front from the back then cut off the modular catch tangs with a dremel to give more space.
Inserting the antenna down through one of the grommets makes it totally weatherproof.
If opening it up in damp or humid weather, I chuck in a dessicant bag before closing it to mop up any residual moisture in the box. -
Hi ，
Is it brand new plastic box?are you goona do some test for something?I would like to help if anything here,tks.

Jalina@Jalina-He If that question was directed at me - No, it is not new, but 6 years old but as yet unused - You can see the original 4 module tangs still uncut through the clear plastic window.
- I bought 2, 3 and 4 module cases at the same time and tried slightly cheaper copies which failed over time (leaked, transparent plastic degraded), the Gewiss originals remain almost as new despite years of exposure to snow, rain and UV - Higher quality.
eg - This is the smallest one used, a 2 module unit serving as a wiring junction box between the pump station and the Node, with an ultrasonic sensor control board mounted in the front section for quick swap should it become faulty.

Hi，Zboblamont，
Very glad to hear news from you,what about ultrasonic sensor control board mounted in other place,eg at the behind would be safer and waterproof?how many QTY do you need ,we can figure it out the best solution if really nail on it,tks.

Jalina@Jalina-He I'm not sure I understand your question over position of the ultrasonic board - It is mounted forward to enable quick access/replacement via the hinged front access, there is no advantage to pushing it further back.
The hinged access door and the two parts of the box have waterproof seals - The clear plastic window allows quick inspection and to see what leds are blinking - The mounting points on the rear box are on the outside of the sealed compartment.
If Gewiss is available in your market I can totally recommend these waterproof lightswitch boxes. -

It is quite into for this item,what about study the direction for waterproof & dustproof & strong anti-interference,precise approach no blind spot，just try to provide high capability product with rather lower cost,maybe welcome in every market,could you design something product like this? -

I have no vested interest in Gewiss, but I do know from experience that these weatherproof light switch boxes work exceedingly well, which is why I first commented.
eg - My Gas meter node has been in such a box for 6 years now with no signs of any damage to any of the unprotected parts within it, or degradation of the plastics over 6 winters and summers - The only interruption to continuous service has been changing batteries or reprogramming the Node.

What kind of recycle item it is?should be changed any part inside as time goes by,what do you think of PCB ,as time goes by,it could be overdued,tks.

Jalina@Jalina-He Having re-read all 6 of your contributions since you first joined this forum 11 days ago to make sure, it appears you have no interest in nor experience of this hobby.
On your latest odd and final question I am prepared to answer - Plastic can be recycled when it is no longer of use - Batteries - The PCB is as good as the day it was installed - PCB's don't become (sic) overdued.

sorry to make you not quite happy,even though I am not professional on unltrasonic sensor application fabrication, I was trying to solve your any problem here,anyway,all I concern is about your request of component inside,maybe I can find a way to do your favor if you need,thx for understand

i use the simplest boxes that you find,that suface mount with 4 screws and ruber on door.
But be carefull with wall mount screws. if you drill the back of the box ,water come in beind this box. so this ones,the scrfew holes are outside the encosure an box is sealed...
another tip is drill on bottom for pass cables but put some neutral silicone. hot glue let water come in with time because expansion coeficient is diferent that the plastic box and open gaps
