Yarn Sensor

Can anyone send me circuit and description for the project “yarn sensing in autolooms”?

This is the mini project tat we’ve done in electrical engineering, but i dont hav the exact circuit. This uses IR sensors to detect the damage of yarns in autolooms and switches off the loom automatically for any damage in yarn, hence prevents wrong weaving. A processor with relay, motor and 4 sensors were used.
In the LCD display, the length upto which the yarn is to be sensed can be set.

don’t worry about the length.
try to check twice (entry & exit) per insertion.
may be “AND or exclusive AND” logic should serve the purpose.
any way post your solution when you get/find one
