5 Channel Line Following Array Sensor

The 5 Channel Line Following Array Sensor Module is a high-precision infrared sensor array designed for accurate line detection and tracking. It consists of five IR transmitter–receiver pairs arranged in a straight line, enabling robots to detect position, direction, and deviation from a guiding line with excellent reliability.

This sensor module is ideal for line-following robots, robotics competitions, and educational projects, offering fast response, stable performance, and easy integration with popular microcontrollers such as Arduino, ESP32, and Raspberry Pi.
