SmartTECHNOLOGYQ<strong>Light</strong> <strong>Gate</strong>Enter the distance between the two <strong>Light</strong> <strong>Gate</strong>s when calculating Speed from Ato B. This is best done using the detection line on each <strong>Light</strong> <strong>Gate</strong> as a marker.Distance betweenthe two <strong>Light</strong> <strong>Gate</strong>sStartto Input Bto Input ASensing InvestigationsWhen a <strong>Light</strong> <strong>Gate</strong> is used in the Graph or Meter program it will show a value ofapproximately 0 – 5% when the infrared beam is unblocked and 100% whenblocked.The Smart Q <strong>Light</strong> <strong>Gate</strong> can be connected to any input and used with the Sensing<strong>Science</strong> Laboratory Graph program to:1. Time the length of an eventThe <strong>Light</strong> <strong>Gate</strong> can be used to calculatevelocity during an investigation by usingthe interval option to determine the lengthof time the <strong>Light</strong> <strong>Gate</strong> was interrupted.t 1t 2Velocity V =lt 2 - t 1Where l = length of the interrupt card.t 2 – t 1 = the interval time5
