Thanks for reaching out with your question. We actually have a few designs which you will likely find very useful for this.

With two sensors correctly out of phase with respect to your gear, you can detect both speed and direction of the gear as it turns.

If you would like, this can similarly be done with a multipole ring magnet and Hall effect sensors

There are also some informative videos on the subject here
