WEATHER INDEX
At the WEATHER INDEX section, you can press
[ INDEX ]
key to view different weather
index in this sequence:
FEELS LIKE DEWPOINT 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 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.
