naturally ventilated room has any influence on the humidity condensation inside the shoe box and inside the open anti-static bag that is inside that box? I don't know about humidity in my situation

If your container isn’t airtight, there’s little sense in using desiccant.

I don’t know why you think you need air circulation. They’re not animals that need air. It’s totally OK (or even desirable) to have a sealed bag with desiccant inside. It will absorb any moisture in the air inside the bag and hold onto it. You want this. You don’t want new, moist air coming in.

The shoe box will help keep dust away, but has no impact on humidity, long term.

Just buy the metalized zip lock anti static bags (they are NOT expensive) and put your gadget and some desiccant packs inside. If you really want optimal long-term storage, use a vacuum sealer to draw out the air and heat seal the bag.

the reason I keep the antistatic bag open is because I don’t trust it very much it appears to have holes but if I close it with silica inside it will saturate the moisture it will continue to enter and the moisture will get stuck in the bag

the shoe box and the bags inside the box are not airtight in this case have any tips to avoid maximum humidity and condensation?

i bought this ziplock bag and silica gel and i wait 2 months

Uhhh.... what? That doesn’t make sense. Once silica gel is saturated, it simply stops absorbing water. It won’t magically attract water into the bag. If you close the bag with the silica gel inside, the silica gel will get saturated less quickly than with an open bag.

The only advice is to put the things inside an airtight container, be it a food container or another bag.

You know you can go to any pound shop or grocery store and buy zip bags?  And any stationery shop will have small zip bags like you’re waiting on.

Still, you should really order some metalized antistatic bags. They are not expensive on eBay.

If it is not airtight then will any electronics quickly corrode the board?

it has big devices like CRT 29 "TV that is impossible to put in airtight environment and other devices have to leave the airtight and be used once a month to avoid causing problems in the electrolytic capacitors

the ziplock PE bag 0.12mm is a useless bag and did I make a wrong purchase? I need a lot of units so the metallized zip on Aliexpress and ebay is very expensive for Brazil

the storage of my cartridge and some electronics is inside a common bag or anti-static bag both open bags and these open bags inside a closed shoe box on top of the cabinet this type of storage is very harmful due to moisture and condensation corroding the board in short deadline?

You have to be careful about airtight containers because some things will out-gas corrosive chemicals.  It is one thing to have groups of parts sealed inside airtight containers but another to have whole assemblies.

The one I have run across was coaxial cable.  The cable itself was fine but when concentrated, whatever it outgassed was pretty corrosive when concentrated in an air tight container over a long time.

Hmmm. Given his moniker, flag (UK), reference to where he lives (my emphasis),
... and ebay is very expensive for Brazil
and some phrases
... and microSD card the 3 have gold contacts contact how many inserts are needed to remove this golden layer and ...
and the number of new threads he's started since joining 5 days ago (26th June).

....there may be something to your contention.

Have you got it figured yet? or are people going to go round and round in circles forever telling you about the same response to incessant repeats of the same question?

I suspect the latter :(

You don't want to tell me that you have better things to do than repeat and repeat and repeat everything a gazillion times, do you?

I'm not sure who "you" is; you have omitted context.

Copy and pasting a question takes ~zero time.

Answering it, on the other hand, ... :(

I just look for the best way to conserve it when there is no silica gel

Another example of that....

The cable just means that you can measure the humidity in one place, and put the display in another place.

For example, put the sensor in a box, and have the display visible outside the box.

There will be no difference in accuracy.
digital and needle hygrometer have the same precision?

Why do you buy Ziploc bags from Ali Express when every corner store sells them?

Does natural ventilation in a room favor humidity and condensation? poorly ventilated places is better?

Re:  'micksmelanie'  (YES, I don;t know why I'm bothering)...
This is just a 'Warning' to the UN-anitiated, that HERE, like on the 'Quora' forum, we occasionally
encounter wankers who like to play 'semantics'  and THINK they are clever.  Unfortunately, they
only waste the time of the 'knowledgeable' in order to (unbeknownst to themselves) make themselves
appear 'semi' intelligent.  Of course, they FAIL miserably, and are of NO consequence.
