Heyy!
i am working on a project where i have to recognize some arm movements suppose if i am lifting my arm up and down/ right and left, i would like to ask, if accelerometer alone can do this or there are other sensors which have to be used in order to recognize the arm movements.

Is the user holding the phone with that arm? Do you need to just detect movement or absolute position? Does it matter if the arm is flexed at the elbow or the shoulder? Some more details about the project should help.

yes user will be holding the mobile, actually it would be a smart watch but for now i am just developing prototype using mobile device. i want to detect movement of the arm if we take an example of a simple exercise suppose lifting arm up and down or right to left (just like a physio therapist suggest exercises for warm up).

As long as you do not need to distinguish different movements it should be easy. Lifting an arm could easily be detected with the accelerometer as a change of orientation. Left / right will be a bit more difficult, but if you only need to count the number of movements I would try to use the gyroscope here with some filtering.
