8 Channel Infrared Line Detection Sensor Board

Description

8 Channel Infrared Line Detection Sensor Board 

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375″ pitch, making it a great detector for a line-following robot. Each sensor provides a separate digital I/O-measurable output.This reflection sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflection sensor. The module is a convenient carrier for eight IR emitter and receiver (photo-transistor) pairs evenly spaced at intervals of 0.375″ (9.525mm). The lower output voltage is an indication of greater reflection.
