I've used these plastic boxes from CPC (in various sizes) with locking handles for some of my projects.
PS: Just realised, CPC must be just down the road from you @smcgann99 in Leeds !!!
They are just big enough for an ESP and a sensor or two. Sorry, shocking photos!
A capacitative touch sensor picks up a touch from inside the case, though I had to bend the pins through 90 degrees. For temperature etc sensors I put them outside, held in place with a little nylon bolt.
I wire wrap the pin headers.
My only problem with them is that polythene is very resistant to glueing.
To give an idea what I'm looking for, something which actually looks like a professional product, for greater WAF!
(rather than a lunch box stuck to the wall @dynamicdave )
Here is an example, with room for a PCB some buttons and a small display.
Similar but without the cutouts
I have also used these for PIRs etc
If you can find a nice box then you can work out how to fit the gubbins inside
I have a number of small attractive ones that I could part with.... Let me get a picture of them over the next day or so.... I have quantities of 25 to 50 of them...
I have used the Intermatic Outdoor Enclosure in a couple of projects. It meets US wiring standards if installed correctly. The plastic allows Wi-Fi to pass through.
Yeah I know... It's just that I am in Bryce Canyon, Zion National Park and the Grand Canyon for another week . When I return home I'll take photos of the cases
