Overview

The 5 Channel IR Infrared CTRT5000 Line Detection Module is a versatile sensor module designed for line detection and tracking applications in robotics, automation, and IoT projects. This module features five infrared sensors spaced evenly apart, allowing it to detect lines, edges, and obstacles with high accuracy.

Pinout and Connections

The module has a total of 7 pins:

VCC: Power supply pin (typically 5V)
 GND: Ground pin
 OUT1-5: Digital output pins for each of the five infrared sensors

Working Principle

The CTRT5000 module uses infrared LEDs to emit light onto the surface beneath it. When the light is reflected back to the sensor, it indicates the presence of a line or edge. The digital output pins (OUT1-5) will output a high signal ( logic 1) when a line is detected and a low signal (logic 0) when no line is detected.

Code Examples

### Example 1: Line Follower Robot using Arduino

This example demonstrates how to use the CTRT5000 module to create a simple line follower robot using an Arduino board.

```cpp
const int sensorPins[] = {2, 3, 4, 5, 6}; // Digital pins connected to OUT1-5
const int motorForward = 9; // Pin for motor forward signal
const int motorBackward = 10; // Pin for motor backward signal

void setup() {
  for (int i = 0; i < 5; i++) {
    pinMode(sensorPins[i], INPUT);
  }
  pinMode(motorForward, OUTPUT);
  pinMode(motorBackward, OUTPUT);
}

void loop() {
  int sensorValues[5];
  for (int i = 0; i < 5; i++) {
    sensorValues[i] = digitalRead(sensorPins[i]);
  }

if (sensorValues[0] == 1 && sensorValues[1] == 1 && sensorValues[2] == 0 && sensorValues[3] == 0 && sensorValues[4] == 0) {
    // Line detected on the left, turn left
    digitalWrite(motorForward, LOW);
    digitalWrite(motorBackward, HIGH);
  } else if (sensorValues[0] == 0 && sensorValues[1] == 0 && sensorValues[2] == 0 && sensorValues[3] == 1 && sensorValues[4] == 1) {
    // Line detected on the right, turn right
    digitalWrite(motorForward, HIGH);
    digitalWrite(motorBackward, LOW);
  } else {
    // Line detected in the middle, move forward
    digitalWrite(motorForward, HIGH);
    digitalWrite(motorBackward, LOW);
  }
  delay(50);
}
```

### Example 2: Edge Detection using Raspberry Pi (Python)

This example demonstrates how to use the CTRT5000 module to detect edges using a Raspberry Pi and Python.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

sensor_pins = [17, 23, 24, 25, 27]  # GPIO pins connected to OUT1-5
edge_detected = False

for pin in sensor_pins:
    GPIO.setup(pin, GPIO.IN)

try:
    while True:
        sensor_values = [GPIO.input(pin) for pin in sensor_pins]
        if 1 in sensor_values:
            edge_detected = True
            print("Edge detected!")
        else:
            edge_detected = False
        time.sleep(0.1)
except KeyboardInterrupt:
    GPIO.cleanup()
```

Note: In both examples, the sensor module should be connected to a power supply and the digital output pins should be connected to the microcontroller or single-board computer. The code examples are for demonstration purposes only and may require modifications based on the specific application and hardware setup.
