UV Sensor Case

Wed Feb 01, 2017 3:48 am

I'm attempting to add on a UV sensor - not a problem - the problem that I am coming across is what to put the sensor IN so that it is weatherproof? All of the more professional UV sensors are encased in a certain type of plastic with what appears to be some sort of tinted plastic/lens. Does anyone have specifics on this? Has anyone successfully replicated one on their own?

Thanks!

Acrylic is transparent to most wavlengths.
Polycarb blocks uv.
I want to try the microscope slide cover glass, it is very thin.
Not sure if it blocks or not

Why not ask the very nice folks at Seeed Studio. They may be interested in building a Grove sensor for you.

Hi,

For building my UV sensor I bought a circular piece of quartz glass (it's used as window in some high temperature furnace for baking clay or so - don't really know how those "ovens" ;) are called ), but I know, the quartz glass don't block UV and IR very much so it's ideal for sensor that measure UV .

I've got 2 ideas for now, picture tell more than I could write :D :

I'm more for v1 because if rain, the water will flow from the glass, and leave a little of residues, unlike in v2 when rain water vapor there will be much more leftovers, and I would have to wipe it more frequently...

As for silicone, I don't need to mention to use UV-resistant one :)

Gavinmc42 Acrylic - you mean PMMA/plexiglass, right?
PMMA is not very good for UV, it actually block it (below 300nm according to wiki), that's why in those big sandwich toasters :P where you can get tan, the fluorescent tubes and glass panels are made from quartz glass.
