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.
