Electrical wiring brown and black only
It depends if in your box you have also neutrals, if you have pigtailed (neutral), usually white, wire inside the box. In that case, you have a 'permanent' phase on the black wires (I'd bet the two wires going to single screw) and a 'switched' phase on the other black wire (that is the wire going to the lamp) and that in newer setups usually is red.

So you'll have all 3 wires needed: PE (bare copper), permanent phase (two wires that now goes on single screw), neutral (white pigtailed wires inside the box).

If you don't have other wires inside the box you should call an electrician to pull a new wire or just remain with current setup.
