I have some pieces of Campbell stuff. Almost all of them surplus (too pricey to buy new) and generally you need to look at these as data loggers (think monthlong monitoring of remote areas like some mountain top). However some are set up to connect to either a phone line, or radio link, or even a satellite link. The controller takes a little bit of programming knowledge and is not necessarily easy to fathom. And they usually end up reading a voltage or pulse from the devices and sometimes you have to use a look up table to get a temperature, humidity or wind speed, or if the characteristics are known, a formula to give you the value you seek.
It is NOT at all like glancing at the Davis or Rainwise or Peet Brothers to see a value on a screen.
On the other hand this is the stuff that the taxpayers spend huge amounts for when durability and supreme accuracy is needed. I think the one in the picture has RM Young sensors for the wind. Those are used in University research, air quality, etc and run close to a thousand dollars.
I'd suggest that you look up the Campbell Scientific web page. The one here in the US and Canada has wonderful downloads of the manuals for the sensors and the data loggers. You can see code snippets to see how they suggest that you interface to the sensors.
To be honest, I bought some on eBay when no one else was bidding on them and got some battleship rugged stuff, and the controllers and link portions of it are sitting in a box for that golden time when I have nothing else to do and will learn how to program them. The sensors got used in other projects. For instance Davis makes a universal anemometer box that will allow you to just screw five wires into the box and it translates the speed and direction into Davis-Talk so it works with the VP2.
I know one of the other members of this board has used it to interface the RM Young 05103 to his station.
Good luck!
