Heat Index
Dew Point
The heat index is determined by the wireless weather sensor’s temperature and humidity readings
when the temperature outdoors is between 80°F (27°C) and 120°F (50°C).
• The dew point is the temperature below which the water vapor in air at constant barometric
pressure condenses into liquid water at the same rate at which it evaporates. The condensed water
is called dew when it forms on a solid surface.
• The dew point temperature is determined by the temperature and humidity data from the wireless
weather sensor.
