Other Weather Station Hardware / Re: Automated Weather Station - Ongoing Build

As far as connectivity goes, I’m using a NL121 Ethernet interface for the CR1000 with which is connected to a PUSR USR-W630 2 port Ethernet/1 port serial to WiFi converter that connects to my LAN. The converter has an external antenna with SMA connector that will have a 2.4 GHz maxrad directional yagi pointed at the building. Figure that was the easiest way to get wired data wireless. The CR1000 can be configured to output a sort of API HTML web page. I have an ESP32 arduino scraping that data and sending it to a SQL database on my web server every 10 seconds.

Wifi really is the easiest and what I'm using too, but if you ever need more range or flexibility in siting you could basically drop in replace your NL121 and PUSR USR-W630 with something like this plugged into the serial port of your logger and another back into a monitoring device on your lan/laptop in the feild:

I'm only going on about it because I've done a bit of Lora and particularly LoraWAN IoT infrastructure deployment particularly with standalone LoraWAN sensors and stations for agriculture/smart cities stuff. Sadly a lot of it is getting edged out by cellular solutions like NB-IOT and CAT-M which I find utterly painful technologies

I've never put thought into LoRa but that is certainly an option. I am fortunate enough that where this station will be sited is on a friends property with clear line of site to his house, so WiFi connectivity is guaranteed. That being said for others I cannot say the same. The other consideration is getting my data online, simply routing the data through serial is far less robust than having an external device grab the data from a page that is not going to have potential intermittent issues with packet loss causing data cleanliness issues if you will.

Interesting bit about the cell solution. I wouldn't even try to bother with that given you'd have to pay for data. No thanks, just one more thing to worry about.

Also if you don't mind me asking what is the most expensive single sensor you're using on this outfit, and where do you think you got the best deal and bang for your buck putting it together? If one (like me) on a smaller budget, wanted to put together something in a similar modular fashion of yours, where would the greatest areas of economising on sensors and accuracy while still delivering something pretty nice?

While Hi-Fi audio is obvious a completely different market (and mostly aesthetic with questionable technical claims) its an area where there is basically no limit to the money you can spend. You can get a cheap amplifier that might be acceptable, a great one for some real expense, or you could get one true acolytes fawn over priced in the kind area usually only reserved for realestate. I kind of want something professional, but not something priced for a research institution or state meteorology organisation. Is it possible?

Most expensive thing in this system over all was actually the data logger. The Campbell loggers hold their value to a fault, but to their credit will probably last longer than we will. I think the data logger will always be the most expensive component in an automated weather station given how well built they are plus the inherent supply/demand. Now with that being said it will be interesting given CSI has seemingly retired their main lineup of CRBasic loggers in the last 5 or so years (CR3000/1000/800). As such government agencies and educational institutions will inevitably upgrade due to the need for latest hardware with support/calibration. I would wager we see them more available on the market for a lower price in the coming years. And with that being said, you can find good deals on instruments - given you already know what to look for/have experience with the nuances - which just takes trial and error and experience. A lot of the time I see listings on eBay for equipment new or lightly used being sold for seemingly unknown reasons. That or retirement as with the aforementioned reason. A few years ago there were loads of listings for a particular kind of temperature and relative humidity probe (HMP35C) that were listed for pennies on the dollar. Looked to have finally been a stock pile of sorts that finally got auctioned off. I got a few and most looked to have had their RH chip replaced and probably had another couple years left in them. But that is just one example of many instances you may encounters be it on eBay or surplus sites.

You can put something quite impressive together for less or equal to that of a fully loaded Davis station. I actually did this for a friend of mine down in Florida. I assembled and calibrated all of the instruments and shipped it down to him where he put it together on his tripod. He managed to get away with a fully loaded IoT capable station that allows him to log locally every second and send data to my website every 10.

I don't know what your specific budget is or what capabilities you need it to perform such as but not limited to internet connectivity or what have you, but it's not too difficult to pull something off for less than some of the prosumer stations on the market.

I could go on for hours about the price/performance/deals of sensors and their benefits and drawbacks. Ideally going in you know your critical measurements for which sensors you need to pay premium for versus those that you could live with accuracies on the order of ±5% ° etc. Also what you want your station to do, that is essentially the driving factor in cost.

If you want professional but not something receiving an accolade for it's overall existence, you can certainly pull it off. I don't think it is for here nor there for offering services but I would be more than happy to consult a station for you if you wanted to venture into a more substantial system.

Ambient Weather and Ecowitt and other Fine Offset clones / Re: Choice of batteries
« Last post by GeeEmm on April 10, 2024, 07:28:46 PM »
an exception is the WH41 outdoor PM2.5 sensor - it comes with rechargeable batteries - and in spite of having a mini solar panel the batteries need to be recharged every 3-6 weeks. The solar panel slows this process down and would ideally keep them charged.

That is location-dependent.  I have one outdoors under a glass dome in full sun that has been untouched for 18 months, another indoors that gets limited sun that is operating with an external solar panel via the usb port.

Here are mine at 85% coverage and perfectly clear sky until well after the event.

I added the Ecowitt Bird Spikes about three months ago, and I have been happy with it. I have several bird feeders in my yard, and the WH40 had become a frequent perch for those awaiting their turn at the feeder. So far, the birds do not seem interested in the Stratus. [ You are not allowed to view attachments ]

Your post crystallises a thought that has been growing in my mind - I have one of those too, and while the birds (still) love my WH40 with the new spikes, my (identical to yours) manual gauge is untroubled by them.  I think I need to find someone with a 3D printer and try the extension ...

There are a few that have reported this. I have not experienced it , it appears to happen , although rarely

Yes, I am one of those, two failures is quick succession, one a brand new unit, the third has been going now for over a year without failure, well other than bird-related problems  ](*,), my problems were battery consumption too. https://www.wxforum.net/index.php?topic=44280.msg450442#msg450442

Ecowitt customer support has been very good, can't complain about that, but the product QC ... that's a different story.

What are all the NWS frequency?

Hmmm….

Being its just a “T” at the top would the gray schedule 40 1 1/4
conduit work you think with glued fittings. Went up and down the isles lol and 1”-11/4” threaded pipe put together weights more than the whole 11ft section of mast i have up
Wont bend for sure but a good wind probably rip the whole thing down

The whole thing is a hiccup, fault, screw up, failure, whatever you want to call it.
The point is, it doesn't actually affect data display or logging as far as I can see. It just another stupidity from WU that may or may not be solved.

The message is obviously an error that can safely be ignored.

EMT uses couplers , a sleeve, with screw pressure to the conduit, wide variety, including Ts. You will need to cut the conduit to length (jig saw , hacksaw) , for what you need, and once you figured out diameter

The heavy pipe you speak of is schedule 40 , and yes it has weight , for your use, stick with EMT.

Frankly, I can't provide more guidance, but, you are going out of the box, you need to work it out :). I have no doubt it can be done

Edit: Also wander down the hardware aisle and look at U-bolts for when you need to do a side by side pipe
