This IR LED/phototransistor pair 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 30 mm. This version features a traditional-style QTR sensor without lenses.
Specifications:
Dimensions: 7.5 × 20.0 × 2.5 mm
Operating voltage: 2.9 V to 5.5 V
Sensor type: QTR
Sensor count: 1
Full-brightness LED current: 30 mA (independent of supply voltage)
Max board current: 32 mA
Output format: digital I/O-compatible signal that can be read as a timed high pulse
