The 4-Channel Line Tracker sensor provides an easy way for line tracking. A line sensor is composed of a number cells and each cell is composed of a sender and a receiver. The particularity of this sender/receiver pair is that it sends light that shall be reflected by the line to be detected but not by the eventually opaque background surrounding this line. Any sender/receiver pair that is able to make a difference between a line and the rest of ground (of a different color) can be used in a line sensor.

VCC pin is connected to 5V , GND pin is connected to the GND, S1, S2, S3, and S4 pins are connected to the digital I/O pins 2 – 5 but you can use others


  • Operating voltage: DC 3.3V-5V
  • Operating Current:>1A
  • Operating temperature: -10 C – +50 C
  • Mounting Hole: M3 screws
  • Detection distance: 1mm to 60 CM adjustable, the closer the distance,the more stable performance, and white reflection farthest.
  • Output Interface: 6-wire (1234: signal output, +: positive supply -: ground)
  • Output signal: TTL level

Pin Connections:

// constants won't change. They're used here to set pin numbers:
const int sensor1 = 2;

int val = 0;

void setup()
    pinMode(sensor1, INPUT);

void loop()
    val = digitalRead(sensor1);
