Looking for a (hidden) sensor detecting people on my ground/house entrance

Maybe try to explain a little bit more how the area/edge looks like and how you want to install/detect people. :bulb:

Depending on that you might also want to try a (light) barrier type of sensor. A modern ToF sensor for example makes a reflector on the second side obsolete and allows easy installation. :point_down:

Next step obviously would be to count the people :people_holding_hands:
