Description
The National Geographic Weather Center weather station with an external wireless thermo-hygro sensor is capable of recording changes in barometric pressure and, based on these changes, displaying a short-term forecast for the near future. In addition, the weather station measures and displays information on the temperature and humidity inside and outside the premises, the magnitude of atmospheric pressure and the phases of the moon.
National Geographic Weather Center Features
- Ability to work with five external temperature and humidity sensors.
- Registration of current, minimum and maximum temperature and humidity separately for each external sensor.
- Individual setting for each sensor of the temperature at which the sound signal is triggered when the temperature goes beyond the set limits
- Possibility of alternate display of readings from each sensor on the weather station display. Switching readings between sensors every 5 seconds
National Geographic Weather Center Features
Weather forecast:
- The weather station is capable of recording changes in barometric pressure and, based on these changes, displaying a short-term forecast for the next 12-24 hours in the form of barometric weather forecast symbols.
Atmospheric pressure:
- Units of measurement: mbar/ hPa, inHg, mmHg(mm Hg)
- Measurement range: 500 to 1100 hPa (14.75 inHg to 32.44 inHg; 374.5 mmHg to 823.8 mmHg)
- Measurement resolution: 0.1 hpa (0.003 inHg, 0.08 mmHg)
- Measurement accuracy: +/- 5 hpa (0.015 inHg, 0.38 mmHg)
- Indication of pressure change trend
- Atmospheric pressure change chart for the last 24 hours
- Possibility of displaying the pressure above sea level and the actual pressure at the installation site of the weather station
Room temperature:
- Units of measurement: ºС or ºF
- Measurement range: -9.9°C to +60°C ( 14.2°F to 140°F )
- Measurement resolution: 0.1°C or 0.2°F
- Fixing Min/Max temperature values
- Update readings every 10 sec
External temperature:
- Units of measurement: ºС or ºF
- Measuring range: -40°C to +80°C (-40°F to 176°F)
- Measurement resolution: 0.1°C or 0.2°
- Fixing Min/Max temperature values
- Temperature change chart for the last 24 hours
- Sound signal when temperature goes beyond set limits
- Update readings every 47 sec
Indoor humidity:
- Units of measurement: % RH
- Measurement range: 0% to 99%
- Measurement resolution: 1%
- Measurement accuracy: +/-5%
- Update readings every 10 sec
Comfort level:
- Symbolic indicator of the comfort level in the room.
- The indoor comfort level is a complex indicator that measures the ratio of temperature and humidity and displays the overall comfort level in the room. During the period when central or stove heating is on, the indoor air is greatly dehumidified, and the air humidity can drop to 20%. Dry air has a very negative effect on the general condition of a person, leads to fatigue, drowsiness, exacerbation of allergies and upper respiratory tract diseases, and decreased immunity. The number of positive ions increases in a dry atmosphere, and affects both the physical and mental state of people. The mucous membrane of the nose and throat dries out, resistance to viruses and infections decreases, which increases the likelihood of developing acute respiratory infections.
External humidity:
- Units of measurement: % RH
- Measurement range: 0% to 99%
- Measurement resolution: 1%
- Measurement accuracy: +/-5%
- Update readings every 10 sec
Watch:
- The clock is automatically radio-controlled by a signal from Frankfurt (DCF-77). The signal is based on an atomic clock powered by the Cesium 133 atom and is under the jurisdiction of the Physics and Technology Federal Institute in Braunschweig (Germany). The error is less than one second in one million years. The exact time transmitted by the DCF77 transmitter is official in Germany. The transmitter is located in Mainflingen - 30 km from Frankfurt am Main and with its radius (about 1500 km) covers almost all of Europe and part of Ukraine. Please note that in the eastern regions of Ukraine the signal reception is unstable.
- Possibility of disabling radio control and selecting manual installation
- Time format: 12 or 24
- Alarm: 3 alarms (1 with snooze function)
Calendar:
- Display: date / day of week / month
- Display of days of the week in six languages: English, German, French, Italian, Spanish, Dutch
Sunrise/sunset time:
- Possibility to select geographic coordinates for 133 cities of the world automatically or enter coordinates of your area.
- Ability to view sunrise/sunset for a selected date
- Error: +/- 3 minutes (latitude +/- 50°)
Moon phases:
- Display: 12 moon positions as pictograms
