PURPOSE: A human body sensing device using a pyroelectric infrared sensor is provided to continuously sense a human body on a real time as directional properties of electronic output signals from the pyroelectric infrared sensor are obtained when infrared ray receiving surfaces of each element are opened or closed by an opening/closing plate.;CONSTITUTION: A human body sensing device using a pyroelectric infrared sensor(30) comprises a body case(100), a light collecting case(400), a linear motor(620), an opening/closing plate(610), and a control unit. A space unit(110) is formed in one side of the body case and a through-hole(12) being connected to the space unit is formed in the other side of the body case. The pyroelectric infrared sensor is arranged in the lower part of the other side of the body case and a plurality of elements is installed on an infrared ray incident surface. The light collecting case is composed of a light collecting case body(410) and a central reflecting plate(460). The linear motor makes a transferring body(625), which is penetrated through a vibration shaft(623) extended to the inside of the space unit through the through-hole, reciprocate in outside. The opening/closing plate is connected to the reciprocating motion of the transferring body, thereby controlling the opening/closing of the infrared ray incident surfaces of the elements by using a transferring hole. The control unit controls the operation of the linear motor according to human sensing signals provided from the pyroelectric infrared sensor.;COPYRIGHT KIPO 2013
