This datasheet is subject to change and may be
amended without prior notice.
1 The default measurement resolution of is 14bit for temperature and 12bit for
humidity. It can be reduced to 12/8bit by command to status register.
2 Accuracies are tested at Outgoing Quality Control at 25°C (77°F) and 3.3V.
Values exclude hysteresis and are applicable to non-condensing environments
only.
3 Time for reaching 63% of a step function, valid at 25°C and 1 m/s airflow.
4 Value may be higher in environments with high contents of volatile organic
compounds. See Section 1.3 of Users Guide.
5 Values for VDD=3.3V at 25°C, average value at one 12bit measurement
per second.
6 Response time depends on heat capacity of and thermal resistance to
sensor substrate.
