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.
Value may be higher in environments with high contents of volatile organic
compounds. See Section 1.3 of Users Guide.

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.
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.
Time for reaching 63% of a step function, valid at 25°C and 1 m/s airflow.
