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.
This reflectance sensor module is designed for use with the Zumo shield for Arduino. It has six IR LED/phototransistor pairs that can be used for line following or edge detection; each sensor provides an independent, digital I/O-measurable output. The array draws approximately 40 mA when the emitters are on, and an optional input allows the emitters to be turned off for additional sensing or power-saving options.
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.
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 analog voltage output.

This reflectance sensor module is designed specifically for use with the Balboa 32U4 balancing robot. It features five IR LED/phototransistor pairs that are great for identifying changes in reflectance on the ground directly underneath the Balboa (like detecting or following a black line on a white background). The sensor array offers dimmable brightness control, and each sensor provides an independent output that can be measured with a digital I/O.
