si4432 wireless receiver

I bought the si4432 wireless to make some projects. I linked it to arduino pro mini as described on this image "" (sorry if is coming from another forum).

Now, how to check if the wiring is correct?
Another thing, I want to control a relay linked to arduino with a 433mhz remote control, it is possible? And how?

This is the object I bought ""

Every informations will be appreciated.

Best regards
