QTR-HD-05A Reflectance Sensor Array: 5-Channel, 4mm Pitch, Analog Output
|pitch × sensors||size
|4 mm × 5||21.0 × 20.0||analog||30 mA||93 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 and separate controls for the odd and even emitters. 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.
