QTR-HD-01A Reflectance Sensor
IR LED / phototransistor pair (QTR-HD-01A)is great for precisely identifying changes in reflectivity (such as line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control regardless of supply voltage. Generally, the closer the object is, the higher the contrast between light and dark readings, but highly reflective objects can usually be detected up to about 30 mm. This version has a traditional style QTR sensor without a lens.
