and there’s the FRAM and silicone sensor coating
wow… superfast delivery from FARNELL… top company ! (this is not an advertisement )
- if you don’t have an business account and live in the Netherlands you can order everything from FARNELL through this site -
I also made myself that nice gift.
The video was instrumental deciding me I needed that toy along with my eyes not getting better with time passing.
Now waiting for package…

just to get an idea what industrial sensors and calibrated CO2 meassurement tools will set you back 
here the online store from VAISALA … manufacturer from Finland

Hey @BoRRoZ
I see you’re often here on the forums with many parts ;).
This shield is in my eyes more or less useless… I’ve three of them here… if you’re interested I can check shipping costs and send them to you free of charge!
Simply let me know…
Mat
Hey Mat… tnx, but no I don’t need them… maybe someone closer to you is interested ?
I am working on the sensor and then I can test this cheap enclosure… why do you think its useless ?
Yeah, if someone is interested, simply drop me a message… I’ve three here (used) and maybe one unused… I’m not sure about that 
.
I had them in use with temp sensors for outdoor temperature measurement, ventilation in the shield is very bad and as far as I can say, the plastic is a standard cheap plastic.Temperature readings are easily 5°C (or even more) too high in sun… I moved to a passive radiation shield from davis: https://www.davisnet.com/product/radiation-shield/
Much more expensive (it is also another kind of plastic they use) but it is worth it, I get now much more realistic measurements.
Here two pics of my two installations I’ve done:
Let me know if you have any other questions
Mat
tnx for the info Mat, yes its a cheap plastic enclosure but inside is a very accurate sensor.
I have 2 sensors a meter apart in different enclosures I want to test .
The enclosure in your link is 8x more expensive but if you’ve tested them worth the money I suppose.
btw did you import them to switserland or bought them locally ?
I would also like to see your results, what type of sensors are you using?
I’m using DS18B20 and BME280 in the davis shield, and usem them also in the ‘cheap’ shields (I know, they are not very accurate… for a good accuracy a MCP9808 or similar should be used).
First I tested all sensors (2x BME280, 2x DS18B20) in the same enclosure (davis, as it provides much more space…) and I had an offset of 0.1 - 0.25 °C for the same type of sensor. Afterwards I moved one DS18B20 and one BME280 to the cheap enclosure. That was the way I ‘measured’ the difference. Unfortunately I don’t have the graphs anymore, if you’re interested in them I will recreate them from my mysql data.
ELV has also a swiss site: www.elv.ch
You can directly buy from them and they will take care of all customs related stuff.

I have BMP180, BME280, HTU21D and SHT31 since longtime inside a Davis shield. I can say, that the Bosch sensors are surprisingly different in measuring. HTU21D and SHT31 are nearly identical. There are no other electronics than the sensors inside the Shield. What all sensors have in common: They react quite identical on changes. What also can be a problem: errors in the used arduino libraries. I prefer I2C on this sensors to omit some calculation errors. 
Here you see, that the difference between the two Bosch Sensors is around 1° I think they are designed for mobile phones, where you cannot expect exact weather measurements.

Bosch sensors tend to go very quickly to 100% humidity imho
Yes, the BME280 is not made for temperature measurement (as also stated in the datasheet), for temperature I use the easy to use and easy to place DS18B20 so far. That humidity goes fast to 100% is a real pain yes @BoRRoZ. Maybe I will change it one day…
At least I need temperature, humidity and pressure, and I would like to not interact with too much different sensors…
Maybe this one would be a nice candidate to test, maybe someone has already used it?

It is a small breakout wich holds a Si7021 and BMP280.
there is also is lesser discussed aspect of those cheap I2C sensors… some of them don’t have a ‘real’ I2c bus.
the manufactures do that to avoid license fees.
sure they work with the available libraries, a problem can occure when you put the mcu in deepsleep and then wake up, for example the older sensirion (SHT) sensors had that 'problem
@mat89 did you buy that davis shield online in the ELV shop ? … I can’t find it ( need more coffee)
this tindie UK shop is specialised in sensors (and very helpfull to)
edge connectors- for outdoors use the longer ones So you can mount an O-ring
sorry @BoRRoZ, I’ve missunderstand your question, you mean where I got my Davis shield from, not the cheap shields 
.
I got it from Switzerland from this shop: http://www.meteo-shop.ch/7714?keyword=7714&category_id=0
OK, thank you for the input about the SHT sensors and also the link to tindie. Maybe I should simply try the one from ali and test if it does work or not.
