Wind Chill
When reading the Weather Index display, you can press the INDEX button to cycle through dierent
weather indexes in the following order: Feels Like > Heat Index > Wind Chill > Dewpoint.
The Feels Like temperature index determines what temperature it actually feels like outside, taking
into account factors like wind chill and the heat index.
Wind Chill is determined by a combination of the wireless weather sensor’s temperature and wind
speed data.
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.

Absolute The absolute atmospheric pressure of your location
Relative The relative atmospheric pressure based on the sea level
The built-in barometer can notice atmospheric pressure changes, and based on the data collected,
can predict the weather conditions in the forthcoming 12-24 hours within a 19 ~ 31 mile (30 ~ 50
km) radius.
