Fernando,
I don't know if this will help but...
I am not an engineer and have no hands on experience with this topic. I have
however browsed several magazines just to get an idea of what's going on in
the world. I remember that what you are trying to accomplish is the subject
of many articles in Circuit Cellar INK magazine. It seems that almost every
month they have articles on how to access remote sensors via the web.
I haven't looked lately but I believe they have a web site
(HTTP://WWW.CIRCUITCELLAR.COM) with listings of past articles. The article
files are located at FTP.CIRCUITCELLAR.COM
Check it out, you might find that what you're trying to accomplish has
already been done. At minimum, you should gain some insight as to what is
involved.
