The RH accuracy is defined as the center (red) line shown in Figure 2, which is the average of the two data points

at each relative humidity set-point. In this case, the sensor shows an accuracy of 0.25%RH. The TH02 accuracy

specification includes:

Unit-to-unit and lot-to-lot variation in non-linearity compensation

Accuracy of factory calibration

Margin for shifts that can occur during solder reflow (compensation for shift due to reflow is included in the

linearization procedure below).The accuracy specification does not include:

Hysteresis (typically ±1%)

Effects from long term exposure to very humid conditions

Contamination of the sensor by particulates, chemicals, etc.

Other aging related shifts ("Long-term stability")

Variations due to temperature. After application of temperature compensation, RH readings will typically

vary by less than ±0.05%/°C.
