[wxsig] Wind application

[Dennis Recla]

I am a user of the MaxStream Radios, not the zigbee but their
standard units.  I use them for up to about 15 to 20 miles direct
point to point - distance varies with height and tree cover. But
we use a 6 element 900 mhz antenna at each end, and minimum
coax between radio and antenna.

They have both RS-232 and USB outputs on the radios. We do run
at 9600 baud, so that helps with distance. We typically pay about
$250.00 for each radio from them, in box with RS-232 or the USB
version for the customer end at the PC.  Antennas from TESSCO
cost another $45.00 each.  It's a simple relatively low cost solution
to get RS-232 from one place to another.

I believe that zigbee is for short range applications.....like up
to 100 feet or something like
that.

I have been reading TAPR postings for a few months. Thanks for all the
information you post. I have a question...

I want to put a wind speed/direction sensor on a remote mountain top. I'd
like for the data to arrive on a web server. I don't want a full PC near the
sensing equipment. There is no cellular service and no land-line phone
service - and no power.

I have read about these Zigbee RF modems. Have you ever heard of an
application
using the one-wire sensors, solar power, local battery, and these RF modems
to get data to some base station?

Any insight appreciated.
