Hi! This is my first post. I'm making a device that needs to count rotations. Previously I've used a rotary encoder, but those wear out too frequently and I don't like that the rotation isn't perfectly smooth. I switched to a IR sensor to track the rotations. Right now I'm just putting my hand in …

Yes, both a photo interrupter and a hall sensor will be better than a reflective solution in your case. The hall sensor has advantages in environment where the sensor can get dirty. The optical solution has advantage when it comes to size. You can build systems of almost any size, from small to lar…
