Description
This reflectance sensor array has seven IR LED / phototransistor pairs mounted on a 4 mm pitch. This makes it well suited for precisely identifying changes in contrast and reflectance (e.g., line detection). These modules offer dimmable brightness control, regardless of the supply voltage from 2.9 V to 5.5 V, with optionally separate control of the odd and even sensor channel emitters. The optimal sensing distance is about 0.5 cm or less, but objects with high reflectivity are generally detectable up to about 5 cm.
This version includes the traditional QTR sensors without lenses, and each sensor provides a separate analog voltage output. The maximum LED current is set to 30 mA and the maximum board current is 125 mA.
