The Lacrosse and Oregon Scientific/Huger/Radio Shack types give you
lots of sensors out of the box, but they might not last as long.
I would say that you should avoid LaCrosse equipment at all costs. It is
cheap, fragile, and of low accuracy.
My LaCrosse unit lasted about 6 months before the rain sensor gave up the ghost,
and a little longer before the wind sensor died. It is now nothing more than
a temperature and humidity sensor, and of no value for APRS weather (because
it basically causes the probe software to hang until it times out now that
the wind sensor doesn't report properly).
And from the day I got it, the barometer was a problem, giving extremely poor
quality data (according to the quality control program from the
gladstonefamily.net site).
Get a good one, don't waste money on LaCrosse junk.
Just to chime in again... as if I never have opinions...
I'd like to selfishly concur w/ Tom. Especially if you do join CWOP.
Please get the best quality you can. We really do use your data. I use
it for data assimilation at the surface into weather prediction models.
So does the National Weather Service. Emergency managers use it when
there's wildfires or chemical spills/plumes. DoD uses it to train
meteorologists (they see CWOP and a whole lot of other data on my Texas
Mesonet site, and use it in their training). Getting the data in is
important and getting good data are also important.
I'm proposing a program to look at using weather instruments like the
Davis and Peet gear for more rigorous purposes, assuming we can
incorporate some basic metadata about the hardware and its installation
and maintenance, such as research and climatological applications.
Tom's anecdote about the LaCrosse instruments is grim. I'm sorry to
hear that. The weather business needs lower cost, usable instruments if
we're going to ever get sufficient densification of the observing
network to verify, and improve our forecasts. Taking advantage of the
data offered us from volunteers like APRS-WX and CWOP gets us a long
ways toward that densification. The data *are* important and appreciated.
