Nice enclosure.
Thanks. I am looking more for something like this but in module form:
SHT31-DIS-F (@Mouser)
Mouser price is €2.69 per chip (1000+) which is only €0.26 more than the version without the membrane film.
Based on the prices for Chinese SHT31-D (SHT31-DIS-B) modules starting from €3,47 I think that a (Chinese) SHT31-DIS-F based module with membrane film for around €4 to €5 should be feasible.
So it just may take some time before cheaper modules become available.
I actually meant the other enclosure with the grill.
the idea is to put the node electronics/battery inside enclosure 1 and the sensor free in that Stevenson enclosure… Im waiting for the glue to dry
this node works even when the battery drops to ONE volt …
can be used in and outdoors
2 gateways down…
A couple of suggestions for you. If all the electronic components are on the top of the board, then consider mounting the board upside down as this will help in the event of condensation. Apply conformal coating to the board but take care to avoid blocking sensor holes/vents.
the sensor module has a filter so I think I have to be very carefull applying some coating to the board.
what coating / spray do you suggest … something like this ?
cool enclosure for my RPI gateway
you can 3D print the case too … but I think aluminium looks better
that said… they are very hard to find new (it’s an 'old product) but I’ve found one.
and now repeat 1000 times ’ no I don’t need it ’
I’ve replaced my sensor in my FARS today as the sensor pcb also was damaged by moisture. Now that it works again I’m planning to spray the pcb with plasti-dip (I have a spray can already). As I’m using a SHT15 as sensor I will cover up the ventilation hole of the sensor with a piece of tape when spraying.
Thought I might try the 3D Print version changing the Apple ‘Apple’ Logo to TTN Cloud and doing in Blue/White but sadly the STLFinder link ends up at a 404 error…will go searching when I have a few mins spare…
LOL Jeff … good plan !
Well done thanks - Delivery of White filament due over weekend so…
Damn! Just looked at slicing ready for print and its 2-4cm too big for build platform…guess may have to look at modding/scaling somehow - simple (say) 80% scaling or whatever never seems to work right for parts that ‘fit’…hey hum…
No because you cannot effectively control the spray for this type of application. I would suggest something like this: https://www.amazon.com/gp/product/B004SPJOKK/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
tnx, I searched a bit too on protecting electronics from the elements

but NO spray that’s clear… I would damage the sensor.
you have lorawan car parking detectors… and now this
