QTR-3RC Reflectance Sensor Array SF_SMD ICs supplied as ready to sliceThis compact module packs three IR LED phototransistor pairs onto a 1. 25 0. 3 board. The sensors are mounted on a 0. 375 pitch, allowing this array to be used as a minimal detector for a line following robot. Each sensor provides a separate digital I O measurable voltage output . The QTR 3RC reflectance sensor array requires digital I O lines to take readings. The similar QTR 3A reflectance sensor array is available with analog outputs. Functional
