Description
Ultimate LFR Performance
Whether you are building a simple line follower or a high-speed maze solver, accurate sensing is everything. This module packs 8 independent IR sensors onto a single compact board. This wide coverage ensures that your robot never “loses” the line, even during sharp turns or at high speeds.
Analog Output for Smooth Control
Unlike basic digital sensors that only tell you “Line” or “No Line” (0 or 1), this array provides an Analog Output. This means the microcontroller receives a varying voltage depending on how much of the sensor is covering the line. This data is essential for writing PID code, allowing your robot to make subtle, smooth corrections rather than jerky movements.
Versatile & Easy to Use
The board is designed to be lightweight and easy to mount on any robot chassis. It is fully compatible with Arduino, STM32, and PIC microcontrollers. While optimized for black lines on white backgrounds, it can be calibrated for the opposite configuration.
