Connect the output of your sensor to the 10k resistor, connect the other end to an analog input of the arduino, you can then use the serial plotter to confirm that you are seeing a square wave signal. If you are then you can connect it to an interrupt pin and go from there.
That would be a very good idea to use the serial plotter, so I could identify the output signal I have. I doesn't know Arduino IDE has this tool inside.
It isn't necessary to connect it to a 10k resistor when I use the 5V power of the Arduino for my sensor for now, am I right?
Only thing I need to be sure about is that black = ground, yellow = power and grey is the signal output wire.
