REAL TIME SENSING PYROELECTRIC INFRARED SENSOR MODULE

PURPOSE: An infrared sensor module sensing on real time basis is provided to easily confirm the existence of an object by checking infrared rays even though the object is not moved and to enlarge a range of sensing a human body. CONSTITUTION: An infrared sensor module sensing on real time basis comprises an actuator(200), a vibration shaft(300), a conductor(400), an infrared sensor(500), a fresnel lens(600), an oscillator(700), and a control unit. The actuator generates a displacement so that a moving body moves. The vibration shaft is fixed in the one side of the actuator. The moving body is joined on the vibration shaft to be moved to an axial direction. The infrared sensor is swung in the moving body based on a shaft and sensing an object by irradiating infrared rays. The fresnel lens is installed between the infrared sensor and the object to be sensed and centers on outer infrared rays on one focus. The oscillator outputs voltages to apply to the actuator. The control unit drives the actuator when outputting the signals over the reference value from the infrared sensor. The control unit stops an operation of the actuator when outputting the signals less than the reference value from the infrared sensor.
