Hi Sir:     Due to no reference device, we don't know the actual absolute humidity and its change.     I also can't confirm your results with your enviromental condition.     In our laboratory, temperature chamber and reference device are used to verify sensor performance and accuracy so that test results can be compared with them.     Thank you.   ...

Hi Sir: On the chart red line means the actual speed, and blue line mean the calculated speed by linear accel accumulating? Maybe the linear accle data have a few drift, but it is not so big as your chart showed. Could you keep the sensor horizental to move your wheel? Under this condition, we can calculate the moving speed by accumulating linear accel data or the raw accel data with reducing offset. And these data should sum up to zero or close to approach zero. Could you try these kind of accel data or linear accel data to calculate speed or offer them to us? I also recommand you to try other modes to lool into the results. Thank you.   .     ... View more
