Need help creating network of sensors

Thank you for the responses.

Working on a High Striker. So the path is about 10-20 feet. It will be a vertical track. Each sensor will result in a different action happening on the backend in AWS. I unfortunately do not have specifics around ball size, specific track length. Speed of the ball will vary on the force and precision of the mallet strike.

I am trying to get a decent understanding of which components I should be testing with to enable this old school device into IoT. The break beam sensors seem like they may be a good fit. What would be a good way to send the data from the break beam sensors back to the Yun wirelessly? Or should there be a Yun at each sensor level to be independent results? If it is a single Yun per break beam sensor I think it could be hardwired without issues.

Thank you,
Mike
