As I understand it, code requires that there be a light switch at every door that enters a room so that people entering the room can light it up so they don’t trip in the dark. If I put a ceiling mounted sensor in the room that can detect a person entering the room from any door, does that satisfy the requirement?

Chuck,
The N.E.C. requires "at least one wall switch-controlled lighting outlet" in every habitable room.An exeception allows automatic control for lighting in hallways and stairways and at outdoor entrances.Another exeception allows automatic controls for lighting in habitable rooms "in addition" to the required wall switch or if there is a manual override where the wall switch would customarily be.So I guess the answer to your question is no.

Barry,
I just wanted to tell you I like your posting style. Always informative. This site needs a good, knowledgable Electrician.
Thanks for sticking around...
regards, Mongo
Notice that the switch is near the door on outside entrances and not specified for other doorways. As with so many things if its location is not specified the electrician has to combine standard practices and educated guess. Most of the time the placement is welcomed by the customer. A few time not. Major problems if the customer disapproves after the wiring is in and the drywall is up and painted. I wish more builder would make sure these things were spelled out. Good blueprints save trouble.
