Motion detector for stairways

[slipofff]

Hello, comrades.
In some projects I need to turn on LED on stairway when somebody walk upstairs. But design of usual motion detector like GIRA 2050 or GIRA 2040 is not so pretty. Maybe you have examples of another sensors? Micro or nano.

Sequa has some motion detectors for their stairlighting system. Its not KNX, but the detecion distance fairly short and does not detect motion further in the room.

No. Walking upstairs and downstairs)
In some projects I used https://www.beg-luxomat.com/en-in/pr...s/pico-knx-dx/. We've mounted it uder first and last stair. But it has unexpected behavior.

Yes. Only upstairs and downstairs) Thanks for your recommend, but I'm looking for smaller detector. I decided to use load cell in my next project. We'll install it under first and last stair and connect in to binary input. I cherish the hope that everything will work correctly)
