What is the distance & movement sensor used for?

I was looking to possibly buy this device, but code here requires the light switches in a bathroom to have a timer and be equipped with a motion/presence sensor.  Are there presence or motion sensors built into this unit?  Looking at the specs; I see "Allows adjustment of the distance and the movement to which the sensor reacts." which doesn't exactly make it clear that it can respond to someone entering the room or not.  The rest of the brochure makes me believe that it doesn't have any motion ability given the lack of advertisement on that front, but the calibration section does speak of it.  Unfortunately it lacks the details to confirm that it does what I need it to and I couldn't find any video or blurb from anyone speaking to the fact that it does have that capability.

In the knowledge base, I don’t see any features like presence or motion detection:

actually there is a motion detector that track the finger you use to adjust light.
The motion detector you mention in your post is normally put not on the swithc (that is at hand level) put in a corner of the room, to turn on and keep on the light when someone enter. with shelly 1 and the other switches there is a specific mode that allows to connect directly the PIR sensor to the button.
If you really want to use the device you mentiones you should get a shelly uni plus, connect it to the pir, and let it send messages to the dimmer.
Given howewer that the requirement is to have the light on when someone is in and turn off after one has left the room [since normally it is linked to the extractor] it is really necessary to use the dimmer ? (you you want an all shelly setup there is in teh BLU series a sensor, but the whole arrangement would cost 7 times that just the device ready with sensor/timer/switch ....
