The QTR-8RC reflectance sensor array is intended as a line sensor
and sensors (make sure you solder them in from the bottom of the PCB
including male and female headers and solderless breadboards
you need to assemble the beacon by soldering its components onto its circuit board
QTR-8RC Abstandssensor hub-module The QTR-8RC reflectance sensor arrayThis sensor module has 8 IR LED phototransistor pairs mounted on a 0. 375" pitch, making it a great detector for a line following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power savings options. Each sensor provides a separate digital I O measurable output. Note: The QTR 8RC reflectance sensor array requires digital I O lines to take readings. The
