title: Tinker Kit 2 axis gyro unknown sensitivity
body: <p>I am reading the Tinker Kit 2 axis gyro (<a href="http://www.tinkerkit.com/gyroscope-4x/" rel="nofollow">http://www.tinkerkit.com/gyroscope-4x/</a>) with the ADC of my Atemga8. I am not using an arduino board nor am I using the tinker kit shield for the interfacing of the sensor board.</p>
  
  <p>The datasheet of the gyro (LPR5150AL), which is mounted on the Tinker Kit claims the sensitivity to be either 0.67 or 0.167 mV/deg/sec depending on whether the output is amplified or not. Futhermore, it claims the zero-rate level to be 1.23 volts. When I read the output of the Tinker Kit when it is at rest I get a voltage around 2.5 Volts. I guess that the board internally converts the voltages. Can anybody now tell me what the correct sensitivity is because if I use the ones indicated in the datasheet I get wrong results e.g. the angular velocity is way too high. I tried to correct the sensitivity with the ratio of the upper named voltages (correction_factor = 2.5/1.23). Now the results are  more plausible but I want to make sure if this is correct and if not what is the correct sensitivity?</p>
  
  <p>Thanks in advance!
