Questions relating to designing PCBs

Hello,
My application is prity simple.
I am trying to control a 3v realy with an xbee.
The problem here is that the xbee doesnt supplie enough power.
I found a small transistor in my tool box(2N1904), but he gave me 2.7v free load, and 1.5v between the relay and transistor.

What's the good way to control a relay with an xbee.

BTW, the power source I am using is strong enough to control the relay(tested).

Thank you!
