QTR-HD-02RC Reflectance Sensor Array: 2-Channel, 4mm Pitch, RC Output
|pitch × sensors||size
|4 mm × 2||10.2 × 20.0||RC (digital)||30 mA||32 mA||5 mm|
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 30 mm. This version features the traditional-style QTR sensors without lenses.
