DEW POINT
- The dew point is the temperature below which the water vapour in
the air condenses into liquid water at constant barometric pressure
at the same rate as it evaporates. The condensed water is called
dew when it forms on a solid surface.
- The dew point temperature is calculated from the temperature and
humidity data from the 7-IN-1 wireless sensor.
HEAT INDEX
The heat index, which is determined by the temperature and
humidity of the 7-IN-1 wireless sensor, is displayed when the
temperature is between 79°F (26°C) and 120°F (50°C).
WIND CHILL
A combination of the temperature and wind speed data from the 7-
IN-1 wireless sensor determines the current wind chill factor.
