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:

  • Dimensions: 17.0 × 20.0 × 2.5 mm
  • Operating voltage: 2.9 V to 5.5 V
  • Sensor type: QTR
  • Sensor count: 4
  • Sensor pitch: 4 mm
  • Full-brightness LED current: 30 mA (independent of supply voltage)
  • Max board current: 62 mA
  • Output format: analog voltages (0 V to VCC)
  • Optimal sensing distance: 5 mm
  • Maximum recommended sensing distance: 40 mm
  • Weight: 1.0 g
