The Pololu QTR-HD-13A Reflectance Sensor Array: 13-Channel, 4mm Pitch, Analog Output is designed for precise detection of reflectance changes, such as line detection. It features 13 IR LED/phototransistor pairs and operates within a voltage range of 2.9 V to 5 V. The device allows for dimmable brightness control, independent of supply voltage, with separate controls for odd and even emitters. It is capable of detecting high-reflectance objects up to approximately 40 mm away, with optimal performance at a 5 mm distance.
