Last mounting question, hopefully

Donā€™t know. Based on the chipā€™s datasheet Iā€™m surprised 5-6 m works for weatherc so all bets are off :dontknow:

oh well, only one way to find out :confused: going the other way would cost a fortune in cable x3 :frowning:

Ald old thread about the subject: http://www.weather-watch.com/smf/index.php?topic=48099.0
EDIT: Anoher one whre Sensirion have answered 3-10 m should be fine: http://www.wxforum.net/index.php?topic=14091.0

Good find :smiley: Bottom line, never read the datasheet before you try something :lol:

Carrying the SCK and DATA signal parallel and in close proximity (e.g. in wires) for more than 10cm may result in cross talk and loss of communication.

I guess itā€™s pretty safe. With the serial comm protocol and checksum system I doubt you can actually get wrong values in the data, if thereā€™s a problem I think it will be garbage data that the ISS will reject.

Yep, trial/error was my route there too. As i needed at least 2-3 m back then did i the 5-6m wire as a test as longer wire = easier to get located nicely. I had in mind that it may not work, but it have worked just fine. As its a ā€œnormal, but 6-core phonewireā€ had it been easy to cut and add a new RJ-plug at the end if it not worked. :smiley:

Google for Davis 7346.221

(@weatherc - lowland England != Finland)

Fenland?

:smiley: (though Breckland might be more appropriate for this thread - sure Bashy will explain to the uninitiated)

I didnā€™t know that oneā€¦

Brexitland?

good news re cable all being well, thanks guysā€¦

You would think so wouldnt you, Brexit gets the blame for most :lol: :lol: :lol: not this time though lol

Breckland (or The Brecks) as a landscape region is an unusual natural habitat of England. It comprises the gorse-covered sandy heath that lies mostly in the south of the county of Norfolk but also in the north of Suffolk. ... The Brecks are one of the driest places in England.

IS there another way to mount the OS anemometer on to a 40mm pole other than attatching a smaller pole, i think the u-bolts are 30mm?

Big assumption that the ISS actually checks checksums? :slight_smile:

True :lol:

Did i say that??
Now i know at least from where not buy possible new Davis-toysā€¦

Finally on the mast, still awaiting the connection for the temp so Davis still not live yet, I am seeing crazy uv requests but they appear when I am working on them, 12uv plus :o



I dont blooming believe it, i made the OS anemometer bird proof and the solar & UV, i left the
Davis anemometer thinking thats prob too small, LIKE HELL IT IS, frigging dovesā€¦ I got it
all nicely setup now too, really didnt want to be bringing it all down again :frowning:

Yes I have had doves sitting on my anemometer on a couple of occasions, but usually on calm days so not a problem for data as such, and nothing broke thankfully. I just had to check for poop in the rain bucket after!! Just one of those things.


Hi Martyn, since my post I had to pull it down again due to a dodgy connector, so whilst it was down I added 2 cable ties to the vane, put it all back up agai, low and. Behold the little basā€¦ Came and perched on the blooming dogleg, thatā€™s only a problem if it stopped the vane, i canā€™t really cable tie that cause it may interfere with the solar and uv :confused:

Aawww, isnā€™t that cute :love8:

Ha ha ha, canoodling on a ya mastā€¦ Thereā€™s only room for one on mine now lol
