NOTE:
-If temperature / humidity is below the measurement range, the reading will show “Lo”. If temperature /
humidity is above the measurement range, the reading will show “HI”.

key
to switch between Outdoor temperature, Feels Like, Heat Index, Wind Chill, and
Dew Point.
4.3.4.1 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.
4.3.4.2 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
4.3.4.3 WIND CHILL
A combination of the wireless 7-IN-1 sensor's temperature and wind speed data determines the
current wind chill factor. Wind chill number are always lower than the air temperature for wind
values where the formula applied is valid (i.e. due to limitation of formula, actual air temperature
higher than 10°C with wind speed below 9 km/h may result in erroneous wind chill reading).
4.3.4.4 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.
