The Cytron Maker Line Following Sensor is a compact infrared sensor module designed for accurate line detection in robotics applications. It integrates a 5-channel IR sensor array capable of tracking lines from 13 mm to 30 mm width while supporting both light and dark line detection. The sensor features a simple push-button calibration system that stores calibration data in EEPROM, ensuring reliable performance even after power cycles. With dual outputs including five digital signals and one analog line-position output, it provides high-resolution feedback ideal for line-following robots using PID control.
