Specification Brand : Optex BulletPoint : Optex EX-35Ri BulletPoint1 : The QTI Sensor is a close-proximity infrared emitter/receiver that is able to differentiate between a dark surface) with low IR reflectivity) and a light surface (with high IR reflectivity) BulletPoint2 : Handy for line following, maze navigation, or sensing the outer rim of a SumoBot ring BulletPoint3 : Wiring options allow it to be used digitally for fast black/white line following, or as an analog sensor to detect different shades of gray. A daylight filter is built into the sensor. BulletPoint4 : What does QTI stand for? Q = Charge, T = Transfer, I = Infrared. When your microcontroller measures the time it takes for the QTI’s capacitor to decay, it’s measuring a rate of charge transfer through an infrared phototransistor. This rate indicates how much infrared is reflecting off a nearby surface.
