In addition, in step (b), the location information of the occupant may include at least one or more of a moving distance, a moving speed, and a moving pattern.

In addition, the sensing region may be divided into nine to thirty, and may be preferably divided into thirty to minimize the measurement error range. In this way, the movement distance of the occupants can be calculated from the position information of the occupants obtained at every predetermined sensing period.

In addition, the one scan time of the PIR sensor 120 may be about 30 seconds, and the movement distance of the occupant of the occupant, which is made for 5 minutes, may be calculated based on each position change detected every 30 seconds.

In order to calculate the moving distance of the occupants, the controller 120 may determine whether the occupant's position information has been received N times from the PIR sensor 200 (S101), and in one embodiment, receives 10 times (5 minutes).
