WEATHER INDEX
At the WEATHER INDEX section, you can press [ INDEX ] key to view dierent 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 signicant in aecting 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.
