MOVEMENT DIRECTION SENSING DEVICE USING INFRARED RAY, CAPABLE OF THE ACCURATE ANALYSIS OF A BOUNDARY LINE MOVING TIME OF A MOVING OBJECT

摘要

PURPOSE: A movement direction sensing device using infrared ray, capable of the accurate analysis of a boundary line moving time of a moving object, is provided to improve the reliability of traveling direction detection by forming the boundary line with same width regardless of distance.;CONSTITUTION: A movement direction sensing device using infrared ray comprises a sensor unit(120), a PCB unit(130), a mirror lens unit(140) and a partition wall unit(150). The sensor unit is comprised of first and second sensors(122,124) and is fixed to a base(110). The sensor unit detects the infrared ray emitted from the human body. The mirror lens unit is arranged to be apart from the sensor unit.;COPYRIGHT KIPO 2011
