Connect the BIGTREETECH Smart Filament Sensor to your Ender 3 Pro or V2. I have this dual gear extruder on my printer which sits up a little higher than other backing plates.

To make changes to the clip, download Smart Filament Sensor Mount.scad and Smart Filament Sensor Back.stl, and open the SCAD file in OpenSCAD. In the customizer, you can change the offset of the clip to the back of the sensor as well as the size of the cutout for putting the sensor onto your printer.
