Claim One:
1. Sensing module for sensing pollution of outside air, the sensing module ( 1 ) comprising at least one electro chemical sensing element ( 3 ), and a processor ( 2 ) for processing a measurement signal of the at least one electro chemical sensing element ( 3 ), the processor ( 2 ) being arranged to provide a sensing module output signal based on the measurement signal and a baseline signal level, and to adapt the baseline signal level with a first baseline adaptation value when the measurement signal is lower than a first threshold level, and to adapt the baseline signal level with a second baseline adaptation value when the measurement signal is higher than the first threshold level and lower than a second threshold level, and to adapt the baseline signal level with a third baseline adaptation value when the measurement signal is higher than the second threshold level.
