Z-wave

Hi

Is there a possability to connect to a z-wave component?
Or is it possible to connect arduino and razperry?
I have an arduino mega and I want to use this z-wave motion detection: http://www.zwave4u.com/Sensoren/Z-Wave-Bewegungsmelder-EVR_SP103::11775.html
When the detector switch the arduino Input port change.

On this site I found a board:

Thanks for your answers.
