sensing (real) human presence, not movement
Posted: 04 Jan 2019, 21:44
hello there,
To build a human presence sensor, I just set up a radar switch (the typical RCWL-0516 board you find in aliexpress), with 3 min histeresys (delay before it considers the room unhabitated), but discovered that often it doesn't detect presence if I'm quite stationary on my seat, since there's not enough movement to activate it.
Did somebody in the forum experience this issue ? Found any solution ?
I found that OMRON developed D6T human presence infrared sensors family: there are 1x1, 1x8, 4x4 array elements sensors.
Does somebody know and/or use them ?
Could they be a WORKING solution for huma presence sensing ?
Have somebody considered something else ?
Regards to you all in the forum....
