IIR Filter options

Values for the press-iir and temp-iir devicetree properties.

Valid values for temperature and pressure IIR filter coefficient.

\‍[ data_n = \frac{data_{n-1} \times filtercoefficient + data_{in}}{filtercoefficient + 1} \‍]

where:

  • $ data_n $ is the current filtered output
  • $ data_{n-1} $ is the previous filtered output
  • $ data_{in} $ is the current input sample
  • $ filtercoefficient $ is one of the coefficient values below

Higher coefficient values provide more filtering (smoother output) but increase response time.
