Depends on the noise bandwidth and sample rate.
A simple 2nd order, critically damped LPF can
do wonders. If you buffer the sensor with an
opamp, this takes just two resistors and two
condensors. I'd use it anyway.

well, 10 bit
is ok, but i would prefer a more accurate resolution.
That's not what I am getting at.
If your sensor's analog output value has less than 0.097656 % (1/1024 * 100%)
noise, then, yes, you need a more accurate ADC. Otherwise there is no point.
