Simon from Wollongong Australia here.
I had a bit of a look through the forum search function but couldn't really find what I was after.
First post and don't know too much at all about the Raspberry Pi, but I would like a cost affective method to receive WIND STRENGTH & DIRECTION from a remote weather station. I'm thinking the best way would be over GPRS mobile (cell) phone, but totally open to ideas. The distance between the weather station and my home is around 20km so wifi is not an option.
What equipment would I need to get this up and running so I could view the data over the web on my home PC or even on my smart phone.
Mobile (cell) phone with charger connected
Raspberry Pi ???
Modem / Router ???
here are a few suggestions for you to consider during your design stage:
rather than using a mobile phone why not use a GPRS modem, uses the same network but should be easier to interface and cheaper (and maybe lower power consumption too).
if you want your weather station permanently powered you will need to consider the worst case solar gain and plan for your system to cope with a week or two of that, if you want it to shut down at night you need to plan for safe shutdown and auto restart conditions.
you should plan for your size constaints, the larger your setup can be the more solar gain you will benefit from, and the more storage batteries you can fit in.
Size ideas: shoe box or suitcase? (probably somewhere in the middle, but where?)
Portability: do you want to be able to easily move the setup or have a fairly permanent installation.
Security: will other people be able to walk off with your setup? how will you stop them? ( a setup in a remote location that no-one visits may not need to worry about this).
Animal proofing: what stops local animals from disturbing your kit?
Waterproofing: water + electronics = bad.
I'd probably be considering something like a briefcase or suitcase sized arrangement, that opens to reveal twin solar panels, beneath the panels are the pi and the GPRS modem on one side and a bunch of batteries on the other side. A socket in the pi side of the case would be provided for the connection to the weather station. another socket in the side of the case would allow an external aerial to be connected to the GPRS modem.
