Pololu QTR-HD-02RC Reflectance Sensor Array: 2-Channel, 4mm Pitch, RC Output

Beschreibung

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.
