Line Sensor Yellow vs. Orange?
For line sensor, my mentor (programming) said that Yellow means receiving no signal, and Orange means receiving signal is powerful.
And when we tried the line sensor, it showed Yellow and Orange at the same time... What does that mean? Thanks ![]() |

Re: Line Sensor Yellow vs. Orange?
Yellow means it sees the line. Orange means its receiving 2.5 times the signal required to activiate. Idieally, you want both yellow and orange. If you just have yellow, it will work.

Re: Line Sensor Yellow vs. Orange?
are they solid lights on the sensors?
we found that we had 2 sensors working perfectly and then went for the 3rd sensor and found out we had plugged it into the wrong port. try checking your wiring to make sure you have it wired right, it should alternate between the 3 i believe... |

Re: Line Sensor Yellow vs. Orange?
Green means that the line sensors are getting less than the required signal required to activate.

And I'm sure I wired it right... It's just I don't understand what's going on with color signs and the color that the sensor is detecting.. |

Re: Line Sensor Yellow vs. Orange?
that means green is not detecting the line?

Re: Line Sensor Yellow vs. Orange?
Green: no line detected
Yellow: line is detected Orange: line detection is POWERFUL. yeh. ![]() |

Re: Line Sensor Yellow vs. Orange?
I've heard the same thing echoed around the forums, and it seems to be true for my testing. What did your mentor hear, and where did he hear it?

she said that green is detecting, yellow is not and orange is receiving powerful signal.... and i guess it was from internet because she was looking at her laptop.... |

I'd suggest checking that out, it might answer some questions you didn't know you had. |

Re: Line Sensor Yellow vs. Orange?
FWIW, our experience is with the Allen-Bradley photoelectric sensors is:
Green = No IR reflected (e.g. pointed at carpet) Yellow = IR reflected (e.g. pointed at gray tape) Yellow + Orange = Very strong IR reflection (e.g. really reflective material) We have the white wire of the sensor wired as the signal to a digital I/O on the digital sidecar. Also, we needed to recalibrate the sensor (turning the sensitivity adjustment knob on the top) when we got the gray gaffer's tape since we had been testing with much more reflective materials before that. |
