3.6 Noise

The noise depends on the oversampling and, for pressure and temperature, on the filter setting used.

The stated values were determined in a controlled environment and are based on the average

standard deviation of 32 consecutive measurement points taken at highest sampling speed. This is

needed in order to exclude long term drifts from the noise measurement. The noise depends both on

humidity/pressure oversampling and temperature oversampling, since the temperature value is used

for humidity/pressure temperature compensation. The oversampling combinations use below results in

an optimal power to noise ratio.
