The presence sensor combines a radar and a PIR sensor and uses ZigBee for communication.
The sensor needs to be pulled from it's supplied mount. Its pin fits nicely into the hole of the corner wall mount.
I noticed that the pin diameter can differ a tiny bit across sensors. If the sensor doesn't sit firmly, you can wind one layer of transparent tape around the pin.
The mount orients the sensor 20 degrees downwards. This works very well in all of our rooms, but you might want to adjust that if your room is particularly small/large. I might also add other versions at a later stage if there is enough demand.
Don't forget to scale the model to your needs in the slicer. This is my first model - I haven't figured out how I can define precise (real-world) dimensions in Blender ;)
I printed the mounts in white PLA, 15% infill, front face down, support only on build plate.
The author marked this model as their own original creation.
