The Weather station samples the barometric pressure every twelve minutes.
These samples are averaged hourly and daily then stored in nonvolatile memory.
The three hour pressure icon change is based off of the last four average hourly
readings.
IMPORTANT:
As the Weather station builds memory, it will compare the current
average pressure to the past forty day average pressure for increased accuracy. The
longer the Weather station operates in one location, the more accurate the forecast icons
will be.
The icons forecast the weather in terms of getting better or worse and not necessarily
sunny or rainy as each icon indicates. For example, if the current weather is cloudy and
the rainy icon is displayed, it does not mean that the product is faulty because it is not
raining. It simply means that the air pressure has dropped and the weather is expected
to get worse, but not necessarily rainy.
