    First tests with the Microwave Radar Movement Sensor RCWL-0516
    that thing is really sensitive over several meters distance!

    I put one in a glass honey jar (without the honey)
    and it works just as well through glass.
    So this can replace the doorbell as it will trigger when anybody comes up to the door.

    Good point, I do not have a cat, but he one from the neighbors often sleeps
    in front of the door and sometimes watches me with big eyes through the glass...

    I tried to make this Doppler sensor directional by wrapping the glass jar in alu-foil
    (as in alu-foil hat) but it is still omni-directional and extremely sensitive:
    http://panteltje.com/pub/wrapped_RF_doppler_motion_sensor_IXIMG_0797.JPG

    Maybe also from the wires to the lab supply, so next is with battery in jar
    and if that does not work make a cantenna:
    https://en.wikipedia.org/wiki/Cantenna
    outgoing wires decoupled with caps....

    For a PIR I need to drill a hole, the idea was just to avoid that with this thing.
    I have a big PIR sensor from the old house.

    I remember reading a story somewhere about how a cat-door was made
    virtually cat-proof to interloper cats just by adding a time delay to
    the detector.

    The cats who lived there would simply jump thru the door, since they
    lived there. Other neighborhood cats would hesitate at the the threshold
    to inspect, setting off the alarm

    earned the moniker "Lucas" as in "Prince of Darkness" :-) This critter
    is so ballsy that he will walk right into my house in search of my cat's food...

    Well he already knows how to get away with the crime!

    But I think an unfamiliar cat just jumping through a door into an
    unfamiliar place violates a deep instinct in a cat, though I'm sure many
    are smart enough to figure out the trick and override that instinct if
    the cat worked at it.

    Randomize the time delay and it might take one a while, though.

    Well, sure, except he doesn't come in if I'm there...he knows better, he
    will get chased. My old cat gets really brave too if I'm there for
    backup! Cat door with an rfid chip reader? If it didn't cost a fortune,
    I might do that :-)
