# 2 MMR Sensors Output

Hi everyone, I am new to the community and I have read all the tutorials. However, I do have a question about the sensor outputs when I use 2 MMR sensors simultaneously.

What I have done is to place a MMR sensor on the upper arm and the second MMR sensor on the forearm. I would like to calculate elbow angle from this. I chose to record Euler Angles. When I export the collected data, I saw pitch, yaw and roll as data output. I have 2 questions as follows:

- Should there be 2 sets of Euler Angles in the spreadsheet (since I have 2 sensors working simultaneously)?
- If not, then I must have misunderstandings about Euler Angles. Can someone kindly point me out how to convert from Euler Angles to elbow angle?

Thanks

There will be 2 spreadsheets. Each with a set of euler angles belonging to a sensor.
