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 &#x2018;ZERO&#x2019; state, a &#x2018;CHECK&#x2019; state, a &#x2018;WAIT&#x2019; state, an &#x2018;AOL&#x2019; state and an &#x2018;IOL&#x2019; 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.
