Accelerometer: different values on different devices?

Question

I am needing to implement a shake recognizer, and I am using the accelerometer on the device to that. However, when I check the values I get from the sensor, it appears that they vary wildly from device to device. For instance, I get a value range of 0-8 as force (after some calculations) on one device, and on the other 0 - 4.

So it looks like they have very different ranges.

Is there anything I can do to make these ranges equal. Or are there some variables that I can use to somehow calculate what a fairly hard shake would be?

Answer 1

According to specification accelerometer should return Measures the acceleration force in m/s2. So it should be calibrated. One thing you could check however is the Sensor class's getMaximumRange() and getResolution()
