Product Description

8-Channel Infrared Line Follower Detection Sensor Board

HighSensitivity 8Bit Detector Module for Line Following Robots

This 8channel infrared line follower sensor module features eight independent IR emitters and receivers arranged in a single board, providing highresolution line detection for robotic projects. It outputs digital 0/1 signals for each channel, making it ideal for Arduino and MCU-based line following applications .

High Precision - 8 independent detectors for accurate line tracking
Adjustable Sensitivity Onboard potentiometers for finetuning detection range
Operating voltage is 3.8V to 5.5V with individual channel outputs
Use a screwdriver to adjust the blue potentiometers for optimal sensitivity based on your track surface
Connect only to 5V if using Arduino; excessive voltage may damage the sensor

Connection and Usage Guide

The module typically includes 3 or 4 pins for power and ground, plus 8 individual output pins for each sensor channel. The I/O pins output a digital LOW when the sensor detects a black (or high-contrast) line, with the exact behavior depending on the mode setting (some modules offer light or dark mode via a jumper).

Pin connections: VCC (5V), GND (Ground), and Out1 to Out8 for the eight detector signals.
If your module includes a mode jumper, adjust it to match your track type (white line on black surface vs. black line on white).
Avoid direct sunlight or strong ambient IR, as this can saturate the sensors and reduce accuracy.

Troubleshooting

Sensor not detecting line:

  • Place the sensor at the recommended 3-15mm distance from the track
  • Adjust the corresponding blue potentiometer using a small screwdriver
  • Ensure the surface is clean and has good contrast between the line and background

Inconsistent readings:

  • Clean the IR emitter and receiver surfaces from dust or debris
  • Reduce ambient IR interference (sunlight, fluorescent lights)
  • Test under stable lighting conditions

All LEDs on/off:

  • Adjust the potentiometer for each channel individually
  • Check the voltage supply is stable within specifications
