8. Operation
8.1 Sensor Verification
To verify correct wiring and test the basic sensor operation, blow on the sensor.
The moisture in your breath should cause the relative humidity reading to rise.
To ensure proper operation, check the output data against a relative humidity
and temperature measuring device such as a psychrometer. Local weather
service data should be used only as a guideline since relative humidity and
temperature can vary significantly over short distances and over brief periods
of time.
