Hi, I am new to this world and I'd like to build some motes to create a WSN.
I'd like to know if all the XBee modules listed in this page Digi XBee Family Features Comparison Chart | Digi International are compatible with the arduino xbee shield, or if there are some exceptions to be taken into account.
Thanks.
with the arduino xbee shield
You say that like there is only one XBee shield. Since this assumption is false, your question can not be answered. Now, for some specific XBee shield (hint, hint), an answer might be possible.
The thing to look at is where the power for the XBee is coming from, and whether that source can supply the needed current.
Thanks for your reply.
I thought this page was referring to a particular (kind of official) XBee shield model for arduino.
It talks about the one made in collaboration with Libelium, so it must be this one: http://www.cooking-hacks.com/index.php/communication-shield-xb-bt-rfid.html .
I also found this (thanks to your enlightening): SparkFun XBee Shield - WRL-12847 - SparkFun Electronics, whose description clearly states "This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version.", which answers my question.
However, so far I've heard about Series 1 and 2, what's series 2.5?
There are better XBee shields than that one, which does not fit well, or allow the use of other shields above or below it, and covers up critical, but not used by the XBee shield, pins. The sparkfun one in your second link is a superior design, in my opinion.
There really are no Series 2 modules. The number 2 was apparently designated to a product that never quite made it to production. By the time the design was production-ready, the number had incremented to 2.5, which, when stored in an int is 2.
And, take what sparkfun advertises with a grain of salt. Read all the comments. Some XBees draw more power than the shield is capable of providing.
Thanks again!
As from the comments, this shield provides a 150mA current, while the digi XBee-PRO module I was interested in, requires 205mA for transmission (specs here).
I wasn't able to find the specs of the Libelium shield.
Which shield would you suggest to use the XBee-PRO module?
Once the Arduino UNO + XBee shield + XBee RF component has been built, will it be possible to add sensors (I am particularly interested in gas sensors) to use it as a mote and build a WSN?

A custom shield with a decent regulator.

Of course.
Alright, thanks again.
Maybe I'll go a bit OT now, but I am willing to understand the basic principles of hardware programming in general.
Arduino shields will use some board pins, for example ETH shield will use pins 10, 11, 12, 13 of the SPI bus.
What if I want to add another shield or something else over the same pins? Will they be no more available?

True. Pins used by one shield can not be used by another shield.
In the case of the SPI pins, though, the SS (slave select) pin defines whether a particular slave (ethernet shield, for example) is actually able to access the pins. If not, the pins could, conceivably, be used for another purpose.
hi there my name is Prakash.im finding issues in finding the peripherals in xbee shield can any one help me this my no 9035402832
