A controller for an environmental sensor provides digital environmental measurement values from analog environmental measurements performed by analog circuitry, the digital environmental measurement values lying in a global scale range. The controller subjects the global scale range to a subdivision into scale subranges that are proper subranges of the global scale range. The controller selects, among the scale subranges, one scale subrange in which an analog environmental measurement is to be performed, selects an offset information and a gain information that are associated with the selected scale subrange and that are indicative of an offset and a gain to be applied by the analog circuitry to perform an analog environmental measurement in the selected scale subrange, and to provide the offset information and the gain information to the analog circuitry.
