The 5-Bit Line Hunting Sensor is a high-performance infrared tracking module designed for autonomous robot navigation and line-following applications. It utilizes five TCRT5000 infrared reflective sensors arranged in a row to provide high-precision detection of black lines on a white background (or vice versa). This 5-channel configuration allows for much smoother cornering and more complex navigation logic compared to standard single or triple-channel sensors. Each sensor features an onboard status LED, providing immediate visual feedback for easy debugging and calibration during the experimental phase.
