I experimented a lot with this - I had trouble with my sensors being too... well. sensitive! I mounted a bedroom sensor directly away from the door and it would trigger as I walked down the hallway. I also agree with the guidance that 'across' a sensor is better than 'toward/away' from a sensor. Some sensors are really strong, others are weak. YMMV depending on which sensor. The sensitivity is also adjustable in some cases so that came into play with me originally.
The one description of it being low to the floor was also an idea I had, but with animal masking I couldn't really get it to work well for me. Ultimately I ended up in the corner of the room on the same wall as the door. it triggers as soon as I step foot in.
Last - I learned the hard way the difference between 'presence' and 'motion'. Our Kitchen table lights would go off while eating dinner - there was no movement in the range of the kitchen! Same problem when watching TV or reading. The lights go on because of motion, but nothing keeps the motion active. I'm not going to carry a presence device in my pocket so... all my rules are written sadly, with longer timers than necessary.
