Pololu QTR-HD-07A Reflectance Sensor Array

Artikelnummer: PO4207

This sensor module has seven (7) IR LED/phototransistor pairs mounted on a high-density 4 mm pitch, making it well suited for precisely identifying changes in contrast/reflectance (like line-detection). Unlike our original QTR modules, these units offer dimmable brightness control independent of the 2.9 V to 5.5 V supply voltage, with optional separate control of the odd and even sensor channel emitters. The optimal sensing distance is approximately 0.5 cm or less, but high-reflectance objects are generally detectable out to around 5 cm. This version features the traditional-style QTR sensors without lenses, and each sensor provides a separate analog voltage output. Max LED current is set to 30 mA, and the max board current is 125 mA.

Overview

These QTR reflectance sensor arrays feature seven 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. Unlike our original QTR sensor modules, these units have integrated LED drivers that provide brightness control independent of the supply voltage, which can be anywhere from 2.9 V to 5.5 V, while enabling optional dimming to any of 32 possible brightness settings. There are separate controls for the odd-numbered and even-numbered LEDs, which gives you extra options for detecting light reflected at various angles.
