10.2 Function return codes

A list of the possible function return codes can be found below.

Sensor OK

Communication error or wrong device found

Trimming data out of bound

Temperature bond wire failure or MEMS defect

Pressure bond wire failure or MEMS defect

Implausible temperature (default limits: 0…40°C)

Implausible pressure (default limits: 900…1100 hPa)

Implausible humidity (default limits: 20...80 %rH)

Error testing is done in ascending error code sequence. This means that if e.g. a trimming data error is

detected (code 20), the temperature plausibility (code 40) is not checked anymore. Instead, error code

20 is returned and no others tests are performed.
