Keyestudio EASY plug Line Tracking Sensor


The Line Tracking Sensor can tell white from in black or black from white accurately.
The single line-tracking signal provides a stable output signal TTL for a more accurate and more stable line.
The working principle is simple, using infrared light's different reflectivity for different color, and converting the strength of the reflected signal into current signal.
This sensor needs to be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.
