barometric pressure because the air pressure is pushing equally in every
direction.
RELATIVE AIR PRESSURE
Relative air pressure is the same as the barometric pressure. The
calculation of relative air pressure is a combination of the absolute air
pressure and the altitude.
ABSOLUTE AIR PRESSURE
Absolute air pressure is the actual air pressure on the barometer without
regard to altitude.
INCHES OF MERCURY (inHg)
Inches of Mercury is the common unit of measurement for air pressure in
the United States.
HECTOPASCALS (hPa)
Hectopascals are the common units of measurement for air pressure in
the International System (SI) of measurement. The hectopascal holds the
same value
Important Note:
The ProWeatherStation TP3000WC comes fully assembled for ease of
use. The Outdoor Sensor array runs mainly on solar power which
charges a supercapacitor located inside the unit but has 2 AA batteries
for backup power when needed (i.e.; solar panel shaded or covered with
snow). The outdoor sensor array communicates with the display console
over a 433Mhz RF signal which sends the data to the display console
about every 16 seconds. The display console can be run on batteries to
display the weather readings or it can be powered using the included 5V
adapter to enable the Wi-Fi capabilities of the display console. When
running on batteries, you must press a key to view the display, Wi-Fi
connectivity is also disabled. Once the unit is connected to a local Wi-Fi
network the display console can upload data automatically to Weather
Underground without the need for a PC and can also be accessed from a
PC running the WeatherSmartIP software.
