This 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. 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 version features the traditional-style QTR sensors without lenses.

Specifications:

  • Maximum range: 40mm
  • Optimal range: 5mm
  • Minimum operating voltage: 2.9V
  • Maximum operating voltage: 5.5V
  • LED current: 30mA
  • Peak wavelength: 940nm
  • Maximum current draw: 125mA
  • Sensor type: QTR
  • Sensor pitch: 8.0mm
  • Sensor count: 7
  • Output type:  A (analog voltages)
