  1. QTR-3A Reflectance Sensor Array
    SKU: POLOLU-2456 Brand: Pololu
    This compact module packs three IR LED/phototransistor pairs onto a 1.25″ × 0.3″ board. The sensors are mounted on a 0.375″ pitch, making this array a great minimal sensing solution for a line-following robot. Each sensor provides a separate analog voltage output.

  2. QTR-1A Reflectance Sensor (2-Pack)
    SKU: POLOLU-2458 Brand: Pololu
    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. This sensor is sold in packs of two units.

  3. QTR-8RC Reflectance Sensor Array
    SKU: POLOLU-961 Brand: Pololu
    This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate digital I/O-measurable output.
