Line Follower Array

Line Follower Array

LE 230.00


The SparkFun Line Follower Array is an extremely accurate line follower module consisting of eight IR sensors. This Line Follower Arrays was designed to follow a dark line of about 1.5 cm width or smaller (you can spray paint or stick an electrical tape) on a light background. Each array is indicated by a LED.  

The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 0.6 to 1.9 cm away. Definitely, this is the ultimate line follower sensor for mobile robot makers and transport automation designers.
