Description

  • Capable of analog or digital outputs
  • Unfocused for sensing diffused surfaces
  • Easily interface with any Parallax microcontroller
  • RoHS Compliant

The Parallax QTI Light Sensor uses a QRD1114 infrared (IR) reflective sensor determine the reflectivity of the surface below it. For instance when the QTI sensor is over a dark surface, the reflectivity is very low and when the QTI is over a light surface, the reflectivity is very high. The QTI Sensors were originally meant to sense the outer rim of a SumoBot® ring; however these little line sensors can be very handy for other applications, including line following and maze navigation.

Features:

  • Capable of analog or digital outputs
  • No contact surface sensing
  • Unfocused for sensing diffused surfaces
  • Daylight filter on sensor
  • Easy to interface with any Parallax microcontroller
  • Dimensions: 1.25 x 0.37 in (31.7 x 9.4 mm)
