I want to deploy widgets around the home, both inside and out, so I needed to find something that would allow some protection from the environment to the electronics, cheaply and easily.
On the weekend while doing some shopping I found the solution in the kitchen area of the local discount store, at $1.50 a piece it was the right fit for the job. They probably won’t like U/V in the long run, but will see how they go, at that price I can replace cheaply.

Waterproof/Dustproof housing with easy access to the internals.
This will be the standard sensor node housing. The widget Boards and battery pack are fixed via velcro so I can easily remove for reprogramming etc.
I still need to look at airflow of sorts for temperature, humidity and pressure sensors, will probably look at putting a couple of small vents in, this will compromise the waterproofing.
To mount these I can put some velcro on the back and mount it on any horizontal or vertical surface.

Same as above, but this is for my outside sensor nodes where I’ve mounted a Solar Cell sealed on the outside, I did some initial testing and there was a filtering effect of the plastic lid and the cell, so I decided to put the cell on the outside to get maximum efficiency, it was a pretty messy job after I used silastic to seal everything, the cell now has a smear of silicone haze across it that is appearing very difficult to remove. So in future I think I’ll live with the slight degraded Cell performance and mount it inside, where it fits perfectly, that way I can use a couple of blobs of hot glue to fix the cell to the lid.
