Wireless Data Transfer Options: RF Module

Found some cheap RF Tx/Rx modules that could be used to send digital data up to 40meters.

Pros: long distance, cheap, seemingly easy set-up with included VirtualWire library from the utube vid

Cons: illegal, limited number of data streams, digital

Perhaps this could be one of a variety of wireless solutions.. Or if we find a niche use for something we want to sense far away. They are cheap, let's buy one and mess around.
