Pololu QTRX-HD-02A Reflectance Sensor Array: 2-Channel, 4mm Pitch, Analog Output, Low Current

Artikelnummer: PO4402

This array of IR LED/phototransistor pairs is great for precisely identifying changes in contrast/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, but high-reflectance objects are generally detectable out to around 50 mm. This version features high-performance, low-current QTRX sensors with lenses.

Overview

These reflectance sensors feature a linear array of IR emitter/phototransistor pair modules in a high-density (4 mm pitch) arrangement, which makes them well suited for applications that require precise detection of changes in contrast, such as line sensing. A variety of sensor counts are available so you can pick the ideal length for your application.
