WEATHER INDEX
At the WEATHER INDEX section, you can press
[ NDX ]
Index key to view different weather index in this
sequence:
FEELS LIKE
DEW POINT
HEAT INDEX
WIND CHILL.
FEELS LIKE
Feels Like Temperature shows what the outdoor temperature will feel like . It’s a collective mixture of Wind
Chill factor (18°C or below) and the Heat Index (26°C or above) . For temperatures in the region between
18.1°C to 25.9°C where both wind and humidity are less significant in affecting the temperature, the device
will show the actual outdoor measured temperature as Feels Like Temperature .
DEW POINT
-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 & humidity data from wireless 5-In-1 sensor .
HEAT INDEX
The heat index which is determined by the wireless 5-In-1 sensor's temperature & humidity data when the
temperature is between 26°C (79°F) and 50°C (120°F) .
Heat Index range
Warning
Explanation
27°C to 32°C (80°F to 90°F)
Caution
Possibility of heat exhaustion
33°C to 40°C (91°F to 105°F)
Extreme Caution Possibility of heat dehydration
41°C to 54°C (106°F to 129°F)
Danger
Heat exhaustion likely
≥55°C (≥130°F)
Extreme Danger
Strong risk of dehydration / sun stroke
WIND CHILL
A combination of the wireless 5-In-1 sensor's temperature and wind speed data determines the current
wind chill factor .
