I surfed about pro relay CAN bus there is no proper explanation ..does it work for this??

@kimot
Exactly @kimot
First thanks for your response

But we are supposed to use hall effect sensor only
Because there is a ring traveler present in the each spindle frame, if there is no breakage occurs it rotate equal to the spindle speed or if breakage occurs , the rotating speed of traveler becomes slow but it wont be getting stopped. Traveler can act as a magnetic substance where the sensor could be easily detected

@rejoe2
"""Put an array of hall sensors to be easily checked with one view in parallel and use hall sensors that will be switched on in case of breakage. This reduces the amount of PINs or other detectors needed."""""
Nice idea ........Thank you @rejoe2
sure will intimate you after testing it

@rejoe2
Actually i am having a spinning industry ,where each individual machine consist of thousands of spindles. In that yarn breakage is major issue occurs , so we decided to place sensor for detecting yarn breakage .
Here hall effect sensor is used for detecting, So we use arduino uno for the testing process .Testing get succeeded but the problem is that it requires many arduino board for thousands of spindle it seems to be much costly.. for that reason we came across this idea
Actually what we needed is.... Is there any possible way to connect particular number of sensor input to one digital I/O pin of arduino board and identify the each sensor
Or for the above problem is there any alternative solution

Thanks @rejoe2
Another doubt rises , while i am surfing related to this
Does it possible with I2C bus protocol ?? or using relay ??

Thanks for your kind reply Boozz ... ..
I searched a lot but i couldn't able to find exact solution for it ..
I found one wire lib for temperature sensors does it works for hall effect sensor???

I am new to Arduino .... I would like to connect my multiple hall effect sensor to one digital I/O pin..is it possible.. if it so how??..please help me....

Hello .. As i am new to arduino and sensor .. i would like to connect my multiple hall effect sensor to one output pin of arduino ... is there any way???
