I'm attempting to use an Arduino Uno to receive the output from a Leuze LV463 Optical Fiber Sensor, but I'm a little confused as to which pin to use on the Arduino.

The thing that is throwing me off is that the sensor has an amplifier where you can set a threshold limit, which when passed triggers the switching signal.

enter image description here

Based on the output signal from the sensor amplifier (as can be seen above), which pin on the arduino should I connect the sensor amplifier output signal wire to, and are there any limitations I need to take into consideration i.e. is the switching signal current too large for the arduino or anything like that?

Thanks in advance!

  • \$\begingroup\$ what is the rate at which you are getting the data?? What is the voltage level at sensor output? Is there anything else that you want arduino to process?? Or just the signal?? Do you also need the on and off time or just the occurrence of 1 n 0 (which seems to be the most likely case) \$\endgroup\$ – Mayank Jul 18 '17 at 6:44
  • \$\begingroup\$ Since you are using optical fibre I believe you are working with high data rates and you don't wanna miss it. So I would suggest you attach the output on an interrupt pin of Arduino. \$\endgroup\$ – Mayank Jul 18 '17 at 6:48
  • \$\begingroup\$ arduino.cc/en/Reference/AttachInterrupt this link should give you the idea about the pin you are looking for. \$\endgroup\$ – Mayank Jul 18 '17 at 6:49
