Abstract
An occupancy detection system uses at least two sensors which are mounted spaced apart in an area to be monitored. A test metric is formed which based on a combination of distances for the at least two sensors. The evolution of the test metric over time enables determination of whether there is a single occupant or multiple occupants in the area to be monitored.
