Range and low power draw mutually exclusive?
Hi all,
I've been trying to solve a data transfer problem for about a year now
and i cant find a cheap solution to what i need. I'm basically
transmitting data (average and gust wind speed) once a minute over a
distance of about 20 miles, over small hills and towns (small hills
being 3-400ft) from a beach location. This location has no power source
and no other means of connectivity. My current method is to chirp the
speeds into a mobile phone continuously and set it to auto-answer so
all i have to do is ring it to find out speeds. However I'd like to
WWW-ize it and so cant get the PC to listen to the beeps all the time,
plus this would cost a fortune call-wise if i could lol.
Can anyone suggest a solution that doesnt draw huge amounts of current
or require loads of space - this is a remote location but still close
enough to towns to have things that look like electronics stolen.
Any hints would be great, this is a personal project so budgets are
small lol.
Many thanks.
James
