Where can i find datasheet for the optical rotary encoder sensor of a mouse :



mine is npn type with open emitter.... i want to interface this sensor with microcontroller...should i connect emitter out put direct to the microcontroller or how can i interface it ?



there isnt anything written on that sensor...do anybody have datasheet ?



That's going to vary with the mouse -- there's no set way to do it.

If it's an open-collector output then you need a pullup to whatever your VCC is, then you can run it to the microprocessor.
