5C1 4 Channel Infrared Tracking Sensor Module IR Line Patrol for Arduino Smart Car

Description

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

Features

• 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

Code:

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


int val = 0;

void setup()
{
    Serial.begin(9600);
    pinMode(sensor1, INPUT);
}

void loop()
{
    val = digitalRead(sensor1);
    Serial.println(val);
    delay(20);
}
