Bigtreetech smart filament sensor

I'm using FW 3 on my duet wifi. Will the Bigtreetech smart filament sensor work with the duet wifi?
There's little info on it but it says it will work with any board with a break detection interface. It looks like it is a rotary sensor but not sure if it is magnetic or optical.

use a continuity tester or voltmeter to see what it outputs...

Hi. Did u succeed using this sensor? Considering getting one to test..
Same question - I just finished making all the cables for my new DUET 2 ethernet setup - and connected the Bigreetech smart filament sensor physically, but haven't found any info on setting up the sensor in Raprap properly....
Since the sensor should work in Marlin 2.0 pretty much seamlessly - maybe we can check in the source? Does anyone have any ideas?

Is this the product you try to connect? https://github.com/bigtreetech/smart-filament-detection-module/blob/master/manual/smart filament sensor module manual191205.pdf
It works also on 3.3V (good), has GND, power and signal wires, and the 'break interface' sounds as an on/off output. In Duet's terminology, this sounds a 'filament run-out sensor' (not to be confused with a 'filament monitor').
@zapta Thanks for the answer.
Yes, that is the product. I have already connected the wiring to the E0 stop properly (+3V, Signal, GND) - but I have seen on the other post (here) that another user has been having problems in setting it in firmware.... it's a pulse sensor it has a rotary encoder (I don't know if it's an optical or magnet one, haven't disassembled it completely). That is why I was asking if anyone had success in setting it up properly...

@omni, if it's a pulse generating sensor, does option #7 here work? https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing
(you will also need to specify pulses per millimeter, the Duet input you are using, and the extruder it relates to)
Thanks for the answer.
I've tried it yesterday - but it seems that Duet is not recording any data from the sensor.
I configured the sensor as following, just to log data when printing :
M591 D0 P7 C"^e0stop" L0.07853981634 R90:110 E3 S0
but it did not receive any data.
Any ideas on what I can try is highly appreciated.

@omni any luck? I have one of these on hand I use on my Marlin machines and would like to use it as well.

@eight_heads lemme answer before he gets online (he's not very active on forum ). it works on his board, the config does not need pullup and need much bigger values as it is low res
so something like
M591 D0 P7 C"e0stop" L7 R50:200 E15 S0
