Hi Karthikeyan,
Please refer the following link;

Xbee is a device based on the Zigbee standard and hence the model like ‘tarang’ or anything else has less significance, I guess. The datasheet of the product will give you more idea about it.
Please start with the interfacing project and post the details regarding the troubles that you face, if there is any.
