2.3. Linearization

Capacitive relative humidity sensors require linearization. The TH02 accuracy specification applies after correction

of non-linearity errors. The recommended linearization technique is to correct the measured relative humidity

value with a 2nd order polynomial; the linear relative humidity (RH) value is calculated as follows:

Where:

their values depend on whether compensation for a typical solder reflow is required

The values for the correction coefficients are shown in Table 8.
