PIR wiring

[Scifen]

Hi guys when adding Pir to a lighting circuit would this be the correct way of wiring so at the light I have 3 core and earth. Black as switch line sleeved brown connected to the permanent feed of the light with the neutral and earth and the brown in a wago. And at the pir have brown as permanent with black sleeved brown a switch line grey sleeved blue as neutral and earth is the correct way of wiring a PIR ??

I think a diagram would help. Also some more information - is this a separate light and PIR sensor, or a combined light/PIR and a slave light driven from it, etc?
