Address 40007: Relative humidity min. peak [R]
Relative humidity minimum detected peak, expressed in tenths of percentage. This value is
stored into device non-volatile memory. Therefore, this value is permanently stored.
To reset this value, a specific action should be taken (acting on address 40102).
Address 40008: Relative humidity max. peak[R]
Relative humidity maximum detected peak, expressed in tenths of percentage. This value is
stored into device non-volatile memory. Therefore, this value is permanently stored.
To reset this value, a specific action should be taken (acting on address 40102).
Address 40009: Temperature offset[R/W]
Default value:0.0°C; Range: ±12.5°C
This value, expressed in tenths of Celsius degree, adds a positive/negative offset to the
sensor measured temperature.
For example, a +100 value of the offset adds +10.0°C to the measured temperature. If the
value of 255 is the measured temperature, the value read in register 0 will be 355
corresponding to 35.5°C.
Address 40010: Relative humidity offset[R/W]
Default value:0.0%; Range: ±12.5%
This value, expressed in tenths of percentage, adds a positive/negative offset to the sensor
measured relative humidity.
For example, a -100 value of the offset subtracts -10.0% to the measured relative humidity.
If the value of 505 is the measured relative humidity, the read value in register 1 will be 405
corresponding to 40.5%RH.

10.6.4 Process data for surface temperature sensor description
Address 40001: System errors[R]
This register is a copy of 40070
Address 40002: Temperature[R]
Detected temperature values, expressed in tenths of Celsius degree. For example, a value
of 100 corresponds to a temperature of 10.0°C. The measurement range is (-40÷125)°C.
