I've been using a gyroscope sensor for an Arduino project. It's all hooked up and working but I have no idea what the units of the data it's giving me are in. I try to spin the board in my hand at what should be roughly 90 deg/sec but I'm getting numbers from the gyro of 2000-5000 range. I've just tried scaling it down and calibrating the scale factor by visually rotating the board 90 deg/sec. I know there has to be a better way to do this. I've been over the data sheet many times and I'm still not getting it. It says the units are mdps/digit which I've never heard of before.

It says the range can be set to 250/500/2000 DPS, which I think is the maximum angular speed the device can measure (i.e 2000 DPS is the fastest setting)
The mdps/digit stands for Milli Degrees Per Second, so (I think) for instance the value of 70 mdps/digit for the 2000 full scale range could be converted to degrees per second by dividing by 1 / 0.07 = 14.286. 1 revolution per second should therefore be 360 * 14.286 = 5413 Make sure you are reading the output registers correctly, the data is a 16-bit value in 2's complement (i.e the MSB is the sign bit, then 15 bits for the value)
Try the above and see how it goes.
