The QTR-1A 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 reflectance measurement is output as an analog voltage.

How is the Pololu QTR-1A different from Parallax’s QTI sensor?
The main difference is in the output interface: the Pololu QTR-1A has an analog voltage output that typically requires an analog-to-digital converter (ADC). Our QTR-1RC is much more similar to the Parallax QTI sensor.
