WEATHER INDEX
At the WEATHER INDEX section, you can press
[ 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 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 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 7-IN-1 sensor .
HEAT INDEX
The heat index which is determined by the wireless 7-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 7-IN-1 sensor's temperature and wind speed data determines the current
wind chill factor .
