There are sensors, and they aren't affected by car seats.
I've an isofix seat and a seat belt secured seat (obviously being seat belt secured any weight sensor is happy because the belt is inserted). Neither have ever caused seat belt warnings. I've had a person sit between the car seats and the car has recognised an unbelted person there.
It's a non issue.
