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

next month its my birthday … So after thinking for a while I decided and ordered one of these
(on youtube)
Have had very good PM communication with the seller So I’m sure everything will be fine.
I finally arrived in the wonderfull world of SMD
and now an oven …
update import duties , transport and fees for the microscope to NL - total € 404,92

found this affordable and apparently dangerous liquid for protecting an outdoor sensor with brush :
Perfect.

I have been using this type of solution for over a decade. One thing you have to look out for, some of this stuff (actually the really good stuff) is incredibly viscous. It will run up the legs of connectors and DIP switches. It is a great insulator. A few times I have had to use a pen knife to clean off excess from connectors which is in itself challenging because you can’t actually see the stuff when it is so thin.

Cant see my workbench anymore… to much stuff and to little space to put it. Anyone has tips on wall mounted boxes / holders for a electronic geek from Holland???
these big plastic stackable drawer boxes fit in cheap ikea bookshelves, so you still have to much stuff but he… you don’t see it

I see an open spot that might fit a 3d printer
LOL…actually i’m moving my little workshop to another room to fit more stuff… like an cnc machine and a 19’ inch rack
Check Aldi. They have wall mounted storage options every so often for around 20 euros.

Thanks for the tips. Im glad I don’t have that much gear;) I love my small storage boxes from the action. Looking for space for all my tools. Printing some holders at the moment for screwdrivers pens etc.
Ok you can stop now!..am starting to get jealous! 
Hope the wife doesn’t see this level of organisation…might set the wrong expectations…

Yesterday I was thinking about an environment sensor in combination with a LoRaWAN mobile device.
Sure you could send every X minutes temp / hum / CO2 / pressure / PM count ect. … it will cost a lot of energy but is it usefull to see that data ‘live’ ?
What if I store some sensors data locally (retrievable later) and only transmit 1, 2, times a day HIGH / time /LOW / time / average /
To try that concept I will mount an 32 kb FRAM on this board on the spot that is reserved for an authentication chip ATECC508A/ATSHA204A.
They are pincompatible and you create 32 kb external I2C storage. (think TTN keys too!)
Coding is straightforward and unlike Flash or EEPROM there’s no pages to worry about.
Each byte can be read/written 10,000,000,000,000 times so almost no wear leveling.
FRAM allows for a lower power usage and a faster write performance. It’s excellent for low-power or inconsistent-power datalogging or data buffering where you want to stream data fast while also keeping the data when there’s no power.
