Pololu QTR-MD-05A Reflectance Sensor Array

• Pololu QTR-MD-05A Reflectance Sensor Array
• Detects precisely changes in reflectance around 40 mm
• Operates from 2.9 V to 5.5 V
• Offers dimmable brightness control

This Pololu QTR-MD-05A Reflectance Sensor Array 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 40 mm.

This version features the traditional-style QTR sensors without lenses.
