Human presence sensors....
-
Does anyone have any suggestions for a 'directional' human presence sensor?
It needs only about 3-4M range but a 90 degree field of view would be ideal for corridor doorway detection.
I have seen some listed online but I believe that they have a 360 degree sense area and this would not be suitable for my application.

There are some new AI based radar nodes that can detect human presence even if a the body is not moving. They use an Serial protocol and should be simple tu use. You can setup alarms within several disctances. I'm still not sure if I want that kind of sensors in my house tbh. But it should be a one weekend project to get it up and running
Maybe I will mount one on my desk to control the lights. And one on the outside of my house, but I will not install many inside the house.
