user14074: This might be a bit of off topic but I have nowhere else to go. :-) I have programmed motion detection with ardruino and would like to integrate it with my home automation system.
Would like to install the PIR in the ceiling of the entrance.
The problem is that all low voltage PIRs for ardruino are sold without any case (just a board).
Does it mean I have to buy a regular PIR (with relay integrated) and modify it?

user14085: This might not be quite the answer you were looking for, but...
3D print your case.
I expect you haven't got a 3D printer but you can find someone on 3D hubs to print it for you, and you might not even have to design the case because thingiverse has a few already...
