openKNX AddOn ToF Sensor Jung LS 990

THE MODEL IS STILL UNDER CONSTRUCTION!

For the construction you need a 3D printer and ideally a CNC milling machine to be able to mill the part according to the DXF. Alternatively, you can of course also drill round holes or mill out the holes by hand with a Dremel or similar.

I also added 2 DXFs for the CNC mill.

You also need to have the AddOn PCBs made, I had them made by JLCPCB.

Simply print the print parts, infill etc. doesn't matter. I printed the lid with support on the tabs.

The assembly is done like this: First assemble the SEN-UP1, we did not need the screw terminals. Then plug the quadruple and quintuple male and female headers together and plug the female part into the SEN-UP1 board and the male part into the AddOn board and solder them. (This automatically aligns them correctly). Then plug the headers for the sensors (except the BME) together and solder them using the spacers.

Once this is complete, the parts can be taken apart again. The AddOn board is screwed into the printed holder with a screw. The SEN-UP1 can then be plugged on and the cover put over it. The whole thing is screwed into the Jung holder frame. The sensors are plugged in with the spacers. 

Now the whole thing can be mounted in the flush-mounted box. Finally, the milled Jung cover with matching frame is mounted.
