PURPOSE: An infrared sensor module is provided to accurately measure a distance between an infrared sensor and an object by measuring the reflectivity of an approaching object. CONSTITUTION: An infrared sensor module(100) comprises a first infrared sensor(110), a second infrared sensor(120), and a control unit(130). The first and second infrared sensors respectively comprise first and second light emitting units(112,122) and first and second light receiving units(114,124). The first and second light emitting units irradiate infrared rays on an object. The first and second light receiving units respectively detect luminous flux of infrared rays reflected from the object. The control unit measures the reflectivity of the object by using the maximum outputting voltage of the first light receiving unit and a distance to the object by using the outputting voltage of the second light receiving unit and the measured reflectivity of the object.
