The QTR-1RC reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following. The output is designed to be measured by a digital I/O line. This sensor is sold in packs of two units.

How is the Pololu QTR-1RC different from Parallax’s QTI sensor?

The two modules are similar, but there are a few noteworthy differences:

  • The Pololu QTR-1RC unit is much smaller, with a 60% smaller board area and 1/3 of the thickness.
  • The module pinouts are not the same, and the Pololu QTR-1RC does not come with 0.1" pins soldered in.
  • The Pololu QTR-1RC uses more current to make the LED brighter.
