My Outdoor Motion Humidity Sensor
-
I have a pretty good experience using the motion sensor outdoors. Been running mine since October on 2xAA batteries (no regulator) and the damn thing is still alive despite cold weather and being triggered 4-5 times a day (not counting the false positives). What is sort of tricky is avoiding is the false positives, e.g. magpies exploring the porch (I have the sensor at about knee level), sunlight rising and falling quickly on a day with spotty clouds and fireworks at New Years Eve. Bottom line, avoid incoming direct light at all cost and put it in a shaded place. Now it is possible that one might filter out those false positives using the sensitivity setting, I don't really know. I also suspect that having dry leaves and stuff get right up close and blow by the sensor is a source of some false positives.

@bjornhallberg If the reading is analog, you perhaps could "weight" the sample. A relatively big change rules out sunlight cycles and perhaps even clouds.
EDIT: See now that the motion sensor is digital. So that would not be possible. But perhaps if combined with a light sensor. -
I wlll put it on the eaves (takfot) without any direct sunlight.
