Depends on what the wall is made of. Wood or concrete should not reduce the range unless there is a lot of wire or reinforcing rod in it. A steel building or stucco on wire mesh will block the signal.

Does anyone have datasheets for those things?
The receiver has one "linear" pin while transmitter
has code input. If the linear output is analog, what
is the resolution? What is the code format used by
transmitter?

The transmitter does not have a code format, it accepts whatever modulation is input. I have not tested it, but believe that a sinewave input to the transmitter will be a sinewave out of the linear output of the receiver.
