Finding out the "Sensitivity" of my gyroscope

Other Hardware Sensors
1

Hello!

I've been following this tutorial on how to make gyroscopes work properly for my project. This part is what i find troublesome .

If you look in the two gyros datasheets (http://www.sparkfun.com/datasheets/Sensors/IMU/lpr530al.pdf and http://www.sparkfun.com/datasheets/Sensors/IMU/LY530ALH.pdf) you will see that the sensitivity is 3.33mV/deg/s for the 4xOUT. To translate these into quids is pretty easy: sensitivity/3.31023.
So in this example I get:
0.00333/3.31023=1.0323.

in the tutorial if you click the link and go find the sensitivity values you can see that his sensitivity is written out as he said, the problem is i don't have this gyro but instead have the MPU-6050, and when i went out to find the gyro sensitivity i found out this data sheet but on it wasn't written anything like he said (LINK - http://www.invensense.com/mems/gyro/documents/PS-MPU-6000A-00v3.4.pdf) here i don't have this mv/deg/s but instead have all sorts of different possible equations and i have no clue what any of it means, also what are quids ? Could anyone be so kind and please explain this to me ?

Thanks in advance!

Page 12 of the MPU6050 data sheet gives the gyro sensitivity:

Sensitivity Scale Factor
FS_SEL=0 131 LSB/(º/s)
FS_SEL=1 65.5 LSB/(º/s)
FS_SEL=2 32.8 LSB/(º/s)
FS_SEL=3 16.4 LSB/(º/s)

This means that if you have FS_SEL set to 0, a reading of 131 corresponds to a rotation rate of 1 degree per second.

Thank you !

Please what does FS_SEL mean??

FS_SEL = full scale select.
