Pololu QTRX-HD-07RC Reflectance Sensor Array

Artikelnummer: PO4307

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 1 cm or less, but high-reflectance objects are generally detectable out to around 5 cm. This version features high-performance QTRX sensors with lenses, and each sensor provides a separate digital I/O-measurable output. Max LED current is set to 3.5 mA, and the max board current is 15 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. 

Two different sensor options are available, denoted by “QTR” or “QTRX” in the product name. The “QTR” versions feature lower-cost sensor modules without lenses while the “QTRX” versions feature higher-performance sensor modules with lenses, which allow similar performance at a much lower IR LED current.

Specifications

  • Dimensions: 29 × 20 × 0.3 mm
  • Operating voltage: 2.9 V to 5.5 V
  • Max LED current: 3.5 mA
  • Max board current: 15 mA
  • Output format: 7 digital I/O-compatible signals that can be read as a timed high pulse
  • Optimal sensing distance: 1 cm
  • Maximum recommended sensing distance: 5 cm
  • Weight: 1.6 g

Note: Unlike most of our products, these sensor arrays do not ship with any headers or connectors included, so you will need to supply your own or solder wires directly to the board to use it.
