This sensor incorporates two QRE1113 infra-red reflectance sensors on a single PCB, spaced just the right distance apart to build a line following robot.

The PCB is symmetrical with snap-off holes across the middle, so you can either use it as a pair or snap it in half to have two separate reflectance sensors.


  • Analog output shows light or dark surface detected
  • Perfect for line following robots
  • Easy interface with Arduino
  • Dimensions: 37mm x 9mm x 3mm
