    摘要: An infrared sensor module includes a first infrared sensor that includes a first light emitting unit configured to emit infrared light to an object and a first light receiving unit configured to detect an amount of infrared light reflected from the object, a second infrared sensor that includes a second light emitting unit configured to emit infrared light to the object and a second light receiving unit configured to detect an amount of the infrared light reflected from the object, and a controller to measure reflectivity of the object using a peak output voltage of the first light receiving unit, and to measure a distance to the object using not only the measured object reflectivity but also an output voltage of the second light receiving unit. As a result, the distance from the infrared sensor to the object can be correctly measured irrespective of the reflectivity of the object.
