Hello,
I would like to integrate my Arduino GIGA into a case to finalize my project. The problem is that I don't know anything about it and my board has to be attached to the box. I've got sensors that I can leave in the box, but some of them have to go outside. How can I do this please? Do you have any references?
So far, it looks like this.
Thank you
aluminium is a conductor so better go for a plastic box (IP66 or IP67?).
e.g.
Not checked if this is the right size 
Thank you !
Is there a way to fix the Arduino in it ? I mean, can I screw it to the box ? This will be inside a room so I don't really need a waterproof case.
Not with normal screws. Either use some insulating PCB Spacers or fix it with small amount of hot glue where the pcb holes are.
Also, don't choose too small box, I would estimate trouble to fit your setup in 120x80mm box.
Great, thank you very much! As I said above, there will be a lot of sensors on the outside of the case, there will only be a few sensors on the inside so I don't need a lot of space. How do I attach my sensors as well? I can't glue them too, can I?
I've also got a GSM, but I don't know if I'll leave it inside the case, as the connection in the room isn't great, so if it's inside the case I don't know how well it'll work...
What do you want the project to look like? Do you want to impress others? Will your project be moved from time to time? How is your project powered and will that be inside the box as well?
My plan is to make it as practical and space-saving as possible. I don't want to impress anyone at all, since it won't be very visible and will be in a room open only to those with access. It won't be moved, and I've got enough cable for sensors that need to be far from the board (flood sensors, for example). It will be powered by usb or usb-c like the GSM, which will be jack-powered, so I need to have enough room to run the power cable too.
You can glue them from corners or you can use bi-adhesive pads. For more professional mounting google: "pcb adhesive base".
Your GSM signal might pass thin plastic enclosure without problems, easy to test before you decide.
OK, thanks! I think the bi-adhesive pads are more suitable because if I want to replace a sensor or just move it, I'll be annoyed if I've glued it before.
For sure if you palm hot glue all over the pcb!
I meant just a drop on the mounting holes
And can't I drill a hole in the box and then screw the arduino into it? Maybe I can buy some special screws. Like that for example ?
I'll see about the sensors, as I think that patafix should be enough for some, but not for others.
Consider your cables to the external sensors. How will they get into the box? Make notches in the box wall instead of holes. So much easier to assemble and modify!
Of course you can, that's what I proposed on post#4.
What's the difference between making notches in the box wall or perforating it? Either way, the box is closed, so I have no choice but to punch holes in it, right? Do you mean that I “cut” a corner of a panel, for example, to get everything through? Sorry if I don't understand.
Notches in the box wall makes it so much easier to change wires and allows multiple wires in one notch.
