Monitoring conditions indoor and outdoor has never been more accessible with the AcuRite Iris (5-in-1) Weather Station. The professional weather station tracks a comprehensive list of weather data, including lightning strikes within 25 miles, temperature (degrees Fahrenheit or Celsius), humidity (percent RH), Wind Speed (mph, kmh or knots), wind direction (with a 16-point wind rose), barometric pressure, heat index, wind chill, dew point, daily and all-time high and low records, as well as the time and date (month/day). The weather ticker on display streams real-time information and alerts for weather conditions. The home weather station's color display features auto-dimming brightness, has a convenient tabletop stand, and can be mounted to any wall. It records historical data, including current, weekly, monthly, and yearly lightning strike counts (miles or kilometers), average wind Speed (at 1, 2, 5, 10, and 15-minute intervals) as well as historical rainfall records (inches or millimeters) for the previous 48 hours, seven days, month, and year. A Weather Center to Monitor Accurate Weather Conditions, Anywhere: This personal weather station allows you to monitor weather conditions in the home, garden, RV park, or any precise location. Enjoy the benefits of an anemometer, rain gauge, wind vane, hygrometer, and thermometer all in one wireless device. Many customers enjoy utilizing this home weather station as a wireless forecast station due to its reliable forecasting technology. Using the built-in weather barometer, the weather station takes 4,000 readings at 12-minute increments to calculate a running average and compute the barometric pressure for your exact location. The pressure accuracy of AcuRite self-calibrating forecasters increases with each new reading over a period of time (Learning Mode). After 14 days, the self-calibrated pressure is reasonably accurate (although the algorithm continues to run; 4,000 readings = 33.33 days) and the weather forecaster is ready for superior weather prediction. The AcuRite 5-in-1 professional weather station with color display and a lightning detector is compatible with up to 2 additional indoor/outdoor sensors (models: 06002, 06044; sold separately) to monitor different locations..
