QTRX-HD-06A Reflectance Sensor Array: 6-Channel, 4mm Pitch, Analog Output, Low Current Logic Analyzer Simple interface requires only two

Simple interface requires only two I/O lines (one for direction and one for speed)

Pololu QTR Reflectance Sensor Application Note

The sensor is small

Works with 0 to 3

which can make it difficult to integrate into projects based on a 0

QTRX-HD-06A Reflectance Sensor Array: 6-Channel, 4mm Pitch, Analog Output, Low Current Logic Analyzer Simple interface requires only twoThis 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 and separate controls for the odd and even emitters. 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
