We continually read adx372 xyz data, and find the variance from each axis is vary large compared with low g sensor under 1g environment . Is it normal?
while do echo -n "x: " cat /sys/bus/iio/devices/iio:device0/in_accel_x_raw echo -n "y: " cat /sys/bus/iio/devices/iio:device0/in_accel_y_raw echo -n "z: " cat /sys/bus/iio/devices/iio:device0/in_accel_z_raw echo "========" sleep 1 doneOutput data (Unit: 100mg)
x:-1 y:11 z:-6
x:-8 y:0 z:10
x:-1 y:9 z:-15 ==> The max difference is 2.5g but test environment is 1g.
Yes, the noise is normal. Please check the noise spec and 0g offset spec on table 1 of the datasheet. If you are only interested in the high g impact signal, you can enable the digital high pass filter…
