Okay, here are the results:
I installed and tested the motion sensor in my 5m x 4m office. I first checked the wireless range, connecting to the Air extension which is 30m away, traversing 3 brick walls. The signal strenght is at -83dBm which is 3 of the 5 blocks in the Loxone Monitor.
Attaching it to the ceiling was easy.
I set it up with the parameter 'Overrun duration' set to 'Short - 3 seconds' and left the parameter 'Sensitivity' to it's default value 'Level 1 - 75%', added the output to a tracker and tested it for 24 hours. It first seemed to function correctly, but then I noticed the sensor did set off on average 2 times per hour with no reason, also during the night with nobody present.
Then I changed the 'Sensitivity' parameter to the other extreme 'Level 4 - 25%'. Now I was not able to set off the sensor at all. I put on some loud hip hop music and asked my colleague to dance around, using the whole room. Nothing.
Only the 2 middle sensitivity levels 'Level 2 - 60%' and 'Level 3 - 40%' were usable, i.e. without false alarms and detecting each time someone walks in or out the office.
Now it definitely is a Motion sensor and not a Presence sensor. I can sit and work at my desk for an hour without setting of the sensor.
The 24V wired and KNX sensors listed as
Suggested Alternatives in this page are far more sensitive when adjusted not to give false detections. A very useful feature of the KNX sensor is that you can dynamically set multiple levels of sensitivity,e.g. you can get a separate signal for presence and for motion, and the levels can be different for day/night, and per sensor. Using the multiple sensors, you can make some directions more sensitive than others.
The detection capability of the Air Motion Sensor is lower than the compared products, however it is a useful product to add on and extend or improve multiple automation functions.
