Nice job, looks great!
What was your highest wind gust? Close to surrounding stations?
tweatherman
Hi tweatherman1, as of yet not much to compare as there has not been any thunderstorms or wind just some on and off rain showers.
45mph verified with other stations, been up just over a year now.
This site gets legit wind, the last windstorm on March 02, 2018 saw a 67mph gust and way back in June of 1980 a nearby tornadic supercell produced baseball sized hail and a 109 mph gust! I have to wonder how a Tempest would fare (with hail) because that storm really did a lot of roof damage and even dented the top of a well built Ducane gas grill!
This has been an absolutely terrible installation. The tin roof amplifies the rainfall amount when it is raining, and when it is windy massive amounts of rainfall are recorded from either roof or mount vibrations.
It has been blowing 45 Knots here today and despite there not being a drop of rain, the Tempest has recorded 235mm!
Looks like it has to come down and go back to the garden. Which is a shame as it is quite sheltered and shaded.
Maybe we need a rubber flexible mount adaptor accessoryâŚIâm now on a mission to think of sâthing so I can raise the height of mine again.
Or some vibration reduction built into tempest itself
Itâs not just vibration. Gusty winds can produce noise within the louvers of the radiation shield itself causing false reports.
Has this claim actually been verified?
the best thing is to mount your sky 30 feet above roofline so you can get proper wind speed and direction. If you have an old sky unit get an 18 inch pipe and fill it with sand. Use the sky that is very low to the ground just to measure precipitation. And you will not have false rain reports increasing your totals. on the app i slide the sky precip in place of the tempest precip card. Never ever had a problem since. Just food for thought. I know some will say it defeats the purpose of the all in 1 unit. But until false rain reports are gone with 50mph winds this is the best scenario.
Whatâs needed is (an expensive!) vibration reduction like what is built into cameras (stabilization).
Or redesign it so the rain sensor is mounted on a 3 axis gimble. But of course, beauty comes before function always (sheesh)
I donât think this is claimed by anyone (certainly not me!).
Itâs been 25 years since Iâve been in a wind tunnel! LOL
That is the place to test it.
Then again, if you rip off the top and desolder the leads from the little piezo transducer and connect to a scope you could compare the output with light/moderate rain to say a fresh breeze blowing through the unit. That wouldnât need a trip to the tunnel for sure.
If youâve seen the transducer youâd know that would be similar to afitting the equivalent of a cheap CCD used in an offshore iphone clone with OIS hardware!
There are other (well known) instrument manufacturers (Vaisala) that have a solid state rain sensor. Piezos tend to be quite sensitive to temperature as well (easily compensated for in this scenario). Ultimately it would be up to the DSP. Thatâs a challenge too since more powerful ASIC needs more wattage. But if this was more of a pro design using a separate power supply mounted lower with a few 100 watt/hr of battery storage and a 100-300W solar panel (depending on geographic location and sun hours, et al) it would be possible. Along with rhime (ice control via heating). But then weâre in a different caliber (and price range!) device.
It sure sounds like you made the claim. Not sure how else to read what I quoted from your post.
Hi,
Any solutions here? Winds over 25km/u will be trigger my weatherstation that it rains. Donât know what I can do to fix this.
Needed a second pole because the diameter was to big, 50mm and not 33mm. The second pole is 2meters long.
Thinking to buy this thing: Amazon.com: Ambient Weather EZ-NPP Tripod and Mast Assembly with Platform : Electronics, but I think it wonât help in my case.
maybe that under wind load the clamps âcrackâ a bit and this is creeping up the pole ??? If you have some rubber that you could use between the pole and clamp ???
Here we go again, Good luck with that (rubber). Edit Rubber is probably a good idea just make sure to tighten any bolts fully.
Your best bet would be to have a tripod of some sort from the top to the ground. But I canât tell how much space there is to work with? Itâll be shaking like a baby with a rattle, at the top.
Someone needs to design a spring mount like a coil suspension type of thang!
Great idea if it can be implemented.

I love the Tempest and this is my second winter with it. One thing I am annoyed with is at -20°C or colder, the wind sensors are affected, assuming by frost. During this deep freeze(temps as cold as -45 in some places) in Western Canada, my wind can barely get above 5 km/h, if it does, it might make it to 10 km/h. So when itâs this cold, I donât even check the wind for my yard. I just use my neighbours 4 houses down since he has a Acurite Atlas which isnât affected this cold weather. Tempest
Youâve now (also) just wiped out a pixel on the image sensor in the camera that took the shot of the burning ball of fire
4001 which needs an overhaul now. The outdoor sensors specifically.
