3.2 RH Accuracy at Different Temperatures

Figure 2 defines the RH accuracy at 25°C, and Figure 5 shows the typical humidity error for other temperature

ranges.

Figure 5. The typical error of humidity in the range of 0~80°C, unit: (%RH)

Please note: The above error is the typical error (excluding hysteresis) of the reference instrument test with a high-precision

dew point meter.

3.3 Electrical Characteristics

The power consumption given in Table 3 is related to temperature and supply voltage VDD. Refer to Figures 6 and

7 for power consumption estimation. Please note that the curves in Figures 6 and 7 are typical natural

characteristics, and there may be deviations.

Figure 6. Typical supply current vs. temperature curve (sleep mode) when VDD=3.3V.

Please note that there is a deviation of approximately ±25% between these data and the displayed value.
