The present invention relates to a human body sensing apparatus with improved accuracy, in which whether a moving direction of a human body is a determinate entry or exit or an indeterminate entry or exit is determined by analyzing a sensing signal outputted from each of sensor units, and room occupancy states are classified into a ZERO state, a CHECK state, a WAIT state, an AOL state and an IOL state depending on a determined result. Even a variety of unexpected behaviors that a human can perform in a sensing area of the sensor units can be detected, and thus correctness and correction rate are superior in calculating the number of people staying in a room. |
