3-Channel IR Line Tracking & Path Detection Sensor Module
3-Channel IR Line Tracking & Path Detection Sensor Module for Robotics
The 3-Channel IR Line Tracking Sensor Module detects lines on contrasting surfaces using three TCRT5000 infrared reflective sensors. Ideal for line-following robots and path detection systems, it provides reliable digital outputs for microcontroller-based projects. Its compact design and adjustable sensitivity make it suitable for both beginner and advanced robotics applications.

What You Can Build With This
- Line-following robot with precise path tracking
- Maze-solving robot for competitions
- Automated guided vehicle (AGV) warehouse navigation
- Smart car lane detection system
Compatibility
The sensor works directly with any 3.3V or 5V microcontroller that accepts digital inputs, including Arduino Uno, Nano, Mega, ESP8266, and ESP32. For 3.3V boards like Raspberry Pi, ensure logic level shifting to protect the GPIO pins. It pairs well with motor drivers and chassis kits for constructing mobile robots.
Wiring Notes
Connect VCC to 5V, GND to ground, and OUT1 (left), OUT2 (center), OUT3 (right) to digital inputs. The outputs go low when a line is detected; adjust onboard trimmer potentiometers to set the threshold for your surface contrast. No external pull-up resistors are needed for most microcontrollers.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the sensor outputs 5V TTL signals that can be read directly by Arduino digital pins without additional circuitry.
Can it detect black lines on a white surface?
Yes, it is optimized for high-contrast line detection; adjust the onboard potentiometers to set the threshold for black-on-white or white-on-black tracking.
Does it come with mounting hardware?
The module includes M3 mounting holes but does not include screws; use standard M3 nuts and bolts for secure attachment.
