Pololu QTRX-HD-31A Reflectance Sensor Array: 31-Channel, 4mm Pitch, an (Item 4431)

Features:

• This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection)
• It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 50 mm
• This version features high-performance, low-current QTRX sensors with lenses
