The  Line Tracking Sensor can detect the white lines in black and black lines in white. The single line-tracking signals can provide a stable output signals TTL, so look for more accurate and more stable line, you can even combine several sensors to meet your specific requirements.  Optional multi-channel mix is easy to install with the necessary line-tracking robot sensors.
