ThermoPro - Live Like A ProCold-Resistant and WeatherproofRechargeable sensor is not only more power efficient but is also completely sealed to be waterproof and cold resistant to ensure transmission in rain or snow, even in temperatures as low as -31°F(-35°C).Barometric PressureBarometric Pressure range：23.62-32.48 inHg (800mbar-1100mbar)Barometric Pressure Tolerance: ±0.059inHg(±2mba)The rate of change of barometric pressure is a important factor for weather conditions.As the weather changes from Partly Cloudy to Sunny, the pressure increases. As the weather changes from cloudy to rainy, the pressure decreases. Displays current barometer pressure with 12 hour history, and an easy to read graph on the trend change in the last 12 hours. With both, you can accurately predict weather condition by yourself.Personal Weather Forecast for your LocationBased on rising or falling barometric pressure, our weather station will forecast the weather 12-24 hours in advance for an area within a radius of approximately 20-30 miles or 30-50 km and inform you via 5 different forecast icons (sunny, partially cloudy, cloudy, rainy, snow) to ensure you're ready for whatever the day throws at you.Responsive, Precise ReadingsLightning quick response time, taking measurements every 50 seconds via 6 highly sensitive vents to provide the most updated and accurate readings available.
