REAL TIME PYROELECTRIC INFRARED SENSOR MODULE

PURPOSE: A real-time infrared sensor module is provided to secure a wide sensing range by fixing the position of an object where infrared ray enters and moving an infrared sensor using a piezoelectric element. CONSTITUTION: A real-time infrared sensor module(1) comprises an actuator(10), a vibration shaft(11), a moving body(13), an infrared sensor(20), a fresnel lens(30), an oscillation part, and a controller. The actuator makes the moving object displace. The vibration shaft is fixed to one side of the actuator. The moving body is coupled to move on the vibration shaft in the axial direction. The infrared sensor is connected to the moving body to move according to the movement of the moving body and senses objects by scanning infrared ray. The fresnel lens is installed between the infrared sensor and the detection target and concentrates external infrared ray to one focus. The oscillation part outputs voltage being applied to the actuator. The controller controls the oscillation part to output voltage, thereby driving the actuator or stop the output of voltage.
