3.5 Recommended modes of operation
The different oversampling options, filter settings and sensor modes result in a large number of
possible settings. In this chapter, a number of settings recommended for various scenarios are
presented.
3.5.1 Weather monitoring
Description: Only a very low data rate is needed. Power consumption is minimal. Noise of
pressure values is of no concern. Humidity, pressure and temperature are monitored.

3.5.2 Humidity sensing
Description: A low data rate is needed. Power consumption is minimal. Forced mode is used to
minimize power consumption and to synchronize readout, but using normal mode would also be
possible.

3.5.3 Indoor navigation
Lowest possible altitude noise is needed. A very low bandwidth is preferred. Increased power
consumption is tolerated. Humidity is measured to help detect room changes. This setting is
