7.7

HUMIDITY_OUT_L (28h)

Relative humidity data (LSB)

Humidity data (see HUMIDITY_OUT_H)

7.8

HUMIDITY_OUT_H (29h)

Relative humidity data (MSB)

Humidity data are expressed as HUMIDITY_OUT_H & HUMIDITY_OUT_L in 2’s

complement. Values exceeding the operating humidity range (see Table 3) must be clipped

by SW.

7.9

TEMP_OUT_L (2Ah)

Temperature data (LSB)

7.10

TEMP_OUT_H (2Bh)

Temperature data (MSB)

Temperature data are expressed as TEMP_OUT_H & TEMP_OUT_L as 2’s complement

numbers.

The relative humidity and temperature values must be computed by linear interpolation of

current registers with calibration registers, according to Table 19 and scaling as described in

Section 8.
