Introduction

Features

Specifications

QTI Line Sensor

The Parallax QTI senor uses a QRD1114 infrared (IR) reflective sensor to determine

the reflectivity of the surface below it. When the QTI sensor is over a dark surface, the

reflectivity is very low; when the QTI is over a light surface, the reflectivity is very

high and will cause a different reading from the sensor.
