Arduino communication to computer

good day. I have developed a device using arduino uno. this device consists of several sensors. gives the values of the sensors to the computer. I've done it but for a single device, multiple devices to a computer that will use and how to take data from all thedevices you need to install a communications network which need to use auxiliary equipment. max 100 and 300 meters betweendevices may be computers. I want to find solutions to the wired and wireless. I would be glad if you help. good work.

Hello etrbet,

I'm trying a similar sort of project but with only one slave device, I have gone for the RS485 communication protocol as it allows up to 32 devices to be connected on one network, over 500m connectivity, simple-ish code please see links below and cheap IC's maxim 485 or equivalent. I'm no where near finished and I'm myself discussing the issue on the forum http://arduino.cc/forum/index.php/topic,91108.0.html . I haven't tried wireless so I can't help there.

Hope this helps

What is your budget?

I would use Ethernet for the wired connections, and perhaps wireless Ethernet for the wireless (if WiFi range is OK). Ethernet is really quite nice for many reasons -- cheap, available parts; people understand it; you can send power over it; ...

If you want longer distance wireless, a 433 MHz long-range link might work, like perhaps: http://iteadstudio.com/store/index.php?main_page=product_info&cPath=7&products_id=127 (I think you need a different frequency in Europe, though -- 315 MHz? Something like that).

thx all of you.
