BFD-1000 5-Channel Infrared Line Tracking Sensor Module

A single IR sensor can only tell a robot whether it's currently over a line, which makes recovering from a lost line or navigating an intersection genuinely difficult. This module solves that with five infrared sensors arranged side by side, giving a line-following robot a full cross-section reading of the track at once - enough resolution to detect the line's position (left, center, right) rather than just its presence, and to recognize junctions and turns as distinct patterns.

An additional front-facing distance sensor with its own adjustable range is built into the same board, giving a robot basic forward-obstacle awareness alongside line tracking without needing a separate sensor and extra wiring. Clean digital high/low outputs per channel mean each of the five line sensors wires directly into a microcontroller's digital input pins, with no analog thresholding needed in code.

Common uses are line-following robot competitions where accurate line position (not just detection) determines steering precision, maze-solving robots needing to distinguish junctions from straight track, and educational robotics kits teaching multi-sensor array logic.
