    Hi Team,h

    In the following video link , the module is accurately discriminating between breathing and movement. Can you please tell which module you are using( Is it X4M200), because in our case we are not getting the result as in the video when we use X4M200 module.

    Thanks & Regards

    It's the prototype of X4M200/X4M300 sensors, but their performance is not exactly the same. which kind of results you are expecting?

    Hi Charlie,

    We want to use it for people detection like occupancy detection, in which we want to differentiate between person and other moving objects like chair movement. And is it possible to reduce the angle of scanning of the sensor to a particular angle?

    Thanks & Regards

    Hi Smithy,
    The FoV is fixed with the current PCB antenna design. See this thread for more explanation on sensor FoV.
    The algorithm is not able to differentiate between a person and other moving objects like a chair, fans, curtain, pets and so on accurately, so artifacts rejection is not robust enough in real conditions. Currently, the solution is to adjust detection range to avoid potential interference.
