Supervision

Hi,
I’m working on a project monitoring (supervision) via a graphical user interface and GSM module.
First of all, I want to choose the temperature/ humidity sensors in the dehumidifying chamber, which I can use it to send (wireless, Ethernet cable) the values.
Also, we have 21 stoves (étuves), it’s have a serial communication port, so I want to convert it and send it (wireless, Ethernet cable).
Therefore, I want to choose the arduino compatible with my project, and choosing the shield which can be useful for all equipment’s.
To sum up, I want to know what the efficient solution well be: using XBEE, Ethernet, or WIFI… and what the components I must use it, to complete my objective?
Thanks

None of these are compatible with the GSM process you mentioned, and then said nothing more about, in your first paragraph.
