Low-Budget Home Weather Stations? 34
Toby Truman asks: "Working at the Fenwick Island Weather Station, I already have access to million-dollar meteorology equipment. However, some tinkerlusting college friends have been asking me about home weather stations, a subject I don't have a lot of experience with. Have any Slashdot users experimented with DIY weather stations, and if so, what do they recommend?"

If the dog is outside the covers, No need for the coat.
If the dog is outside when I wake up, I consider taking the day off it's so nice.
If the dog is under the covers and there is a wet spot at the foot of the bed, I'm not going to work because it must be snowing.

Weather Underground has a nice coolness factor, despite their unfortunate choice of names [loper.org]. Clever icons, well-designed site, yada yada. Please note that, although Weather Underground doesn't have an official AvantGo channel, the printer-friendly versions of the pages work very nicely on handhelds.

* Temperature (from the meter)
* Clouds (look out through the window)
* Wind speed (how fast the cone is dancing around)
* Humidity (how far the cone has opened)
* Snow (is there any on the cone)
That is about as much as you can ever see through a window. If you need to know the wind direction, you have to measure it on top of your home, or somewhat away from any buildings. Same for a measurement of its speed.
Of course, being on slashdot, the proper way is to let someone else do the measuring, and read it off over the net.
OT: Wireless conn. of all these Wx Stations... (Score:2, Informative)
project intended to provide services to
(among other telemetry applications) use
Amateur Radio (as well as other wireless
technologies) to connect users to such
Weather stations... this has applications
to emergency services...
The tasks include:
- Adapt an existing Open Source system
(in Linux/C) to the purpose
- Design & Develope a new one (Linux &
Windows)
Have a look:
groups.yahoo.com/group/OpenAVL
(There is also a SourceForge project area
(details at the above Yahoo site).
For those who know it, we envisage an Open
Source counterpart to the closed-source
UI-View - from the UK - (whose -extensions-
to the open APRS protocol seem -yet- to be
published), combining ideas from the Austrian
program with an extended feature-list.
New talent always welcome... both to [try to]
break it (i.e. test releases) and to fix it.

Then start looking hardware which can be connected to a computer or a microprocessor, e.i. things like wind speed/direction. Other things you can build cheap without loss of precision, f.ex. temperature sensors for $2-4.
What station I use for APRS (Score:1)
Since I am a ham radio operator, I typically use APRS (Automatic Packet Reporting system), in which many hams have their own weather stations attached to, so you not only get the weather data from the nearest airport, etc. But you get it from many, many locations, and it is plotted on a map which can help alot during a fast moving storm.
The station I use is the Peet Bros [peetbros.com]. Ultimiter 2000. This company is very helpful, and they even publish the format of the RS232 data [peetbros.com]!
There are several sites on the net that you can get APRS, such as http://www.aprs.net [aprs.net] and if you're not a ham, you can still usually get data from the 'net since many fixed stations gate their data to the net. There are versions for DOS, Linux, JAVA, Windows, MAC, and possibly more. Also, those "trained weather spotters" you hear the news talk about? Most are hams. Go to http://www.skywarn.org [skywarn.org] to find out more.

The weather stamp is a project kit based on the Basic Stamp microcontroller. If you're not familiar with the Basic Stamps, they're easy to program and very versatile. The weather station is good for a few measurements and only costs between $30 and $50.

I'd suggest searching on Ebay for one. Hopefully, it will come with the manual, which will have the specifics of how to talk to its serial port.
Davis Instruments (Score:3, Interesting)
Eight years later, it's done ok... the biggest problem is the wind sensor gets hit by lightning and it frys the station. The last time this happened, two years ago, I put off repairing it ($75) until I remount and properly ground the anemoneter (wind sensor). This will be one of my summer projects.
The humidity sensor dies every now and then, but Davis almost always replaces it for free. The biggest problem with that is where I mounted it; too high for regular access - I have to borrow a ladder.
I've pulled Cat5e to the attic and I'm about ready to deploy a "weather cam" pointed northeast out of an attic window so I can display realtime images. As the weather station comes back online, there are a number of windoze products out there that will log and create HTML pages with the data coming out of the WMII.
The WMII has been a fun little toy...
An underlying theme is the mounting of the sensors. Every location will be different, but can be a pain. The newer wireless sensors are very appealing, since you could mount them away from a house and not face some of the height/access problems you encounter on a roof top.
If I were to start over, I'd look at the now much richer market place like this:

Many options with many costs.... (Score:2, Informative)
Cabela's (Outfitter for hunting and fishing) has a few options from Origon Scientific like a few other users have mentioned, and I have also see the ones by Davis like your link show. My first recogmendation is find out if they are looking to spend $20 or $700. Then find our what they want to see on it. Temp only or humdity, wind speed with direction, barometer, UV index, and rain fall? Then look into seeing how their home is setup. Can they use wired or should they go with wireless - most wireless transmits on 433Mhz +/- a bit. Not a concern for users of WIFI and whatnot, but might cause trouble with their garage remote system, but I have heard nothing of this sort yet.
I live in an apartment, and I for now and for the past 3 years have used a $20 indoor outdoor thermometer that Radio Shack sells that was designed for automobiles. Works fine, but only delivers the temp. It also has a backlight for early morning/late night viewing. (Helps me decide if it is worth going out to try to see a meteor shower or two this winter dispite all the light polution in the Twin Cities.) It does all I need for now, but when I get a house, I would love to get a wireless system that has wind speed and direction, as well as humidity. BTW, I think the newer version of the Radio Shack Auto thermometer has a "freezing alert" pico buzzer in it now. Might get anoying at times, like 3AM.
One warning about mounting remote sensors, keep them in the shade if they are temp sensors for the obvious reason. Most people forget that though when mounting them. Under a deck, or on the shaded side of the house (usualy the north side if you are north of the equator,) works better than the sunny side. Also remember that the remote transmitters will use and eat batteries unless you buy the solar kits with the rechargable packs on them. They get pricy though. Wires may be a pain, but they are cheeper. That and when it's 20 below and a windchill of 30 below, you will be happy not to have to go outside to change the batteries so you know how cold it is.
Also, check out Target and other discount stores. I have seen a few with remote sensors for under $100 there. Not the top of the line, but still, they give internal temp, humidity and barametric preasure, and I think I saw one with the same three measurement for outside.
Also remind them that they will not be walking around the house/apt. with the reciever after the first week as they will loose the novelty of it. There is no point, IMO, to spen $500+ on something that will be forgotten about in a few weeks. Also, I hate the concept of these programs for windows based computers, but lots of local TV stations will offer a "weather bug" that will sit on the systray and show the current temp outside at the TV station. Drawback, internet connection needed for updates, computer needs to be on, resources are consumed, and most have adds built in to offset the cost of the data feed bandwidth and the development of the program.
