Upload your PWS data, contribute to a global weather network, and share your live conditions with the world
We're building the platform that lets your PWS publish data directly to vweatherstation.com
A personal weather station (PWS) lets you measure your own backyard weather — temperature, humidity, barometric pressure, wind speed and direction, rainfall, UV, and solar radiation — independent of distant airport observations. When you connect your PWS to vweatherstation.com, your data joins a global network of citizen weather observers that improves regional forecasting, supports climate research, and gives your local community access to truly local conditions. Whether you run a budget Ecowitt setup or a professional-grade Davis Vantage Pro2, our upcoming PWS upload platform will support it.
A personal weather station is a complete set of meteorological sensors that you install at your home or property to measure the weather at your specific location. A typical PWS includes a thermometer for air temperature, a hygrometer for humidity, a barometer for atmospheric pressure, an anemometer for wind speed, a wind vane for wind direction, a rain gauge for precipitation, and often UV and solar radiation sensors. The sensors connect to a console or gateway that processes readings and uploads data to weather networks. Modern PWS hardware ranges from compact all-in-one units costing under $200 to professional-grade installations exceeding $2,000.
Official weather observation networks have significant gaps — most airport stations are located in flat open areas that don't represent the microclimates of nearby valleys, hilltops, urban heat islands, or coastlines. Personal weather stations fill these gaps. When you upload your PWS data to a public network, you contribute to better local forecasts, more accurate severe weather warnings in your area, and historical climate records that researchers depend on. Citizen weather observer networks like CWOP, Weather Underground, and the WMO Global Basic Observing Network have collectively produced billions of observations and dramatically improved short-range forecasting in populated regions.
Our PWS upload platform will support all major brands. Ecowitt has become the dominant value brand with the GW1100, GW2000, and HP2551 gateways supporting dozens of compatible sensors. Davis Instruments Vantage Pro2 and Vantage Vue remain the professional-grade gold standard for accuracy and longevity. Ambient Weather WS-2000 and WS-5000 series offer a balance of features and price. AcuRite Atlas combines a respected sensor suite with smart hub uploading. Older Weather Underground compatible stations using the WU upload protocol will be supported through our compatibility layer.
Proper PWS siting matters as much as the hardware. Temperature and humidity sensors should be 1.5–2 metres above ground in a shaded, well-ventilated location away from buildings and pavement. Anemometers should be mounted 10 metres above ground or 3 metres above any nearby obstruction. Rain gauges need clear sky exposure and level mounting. Once installed, calibrate sensors against a reference and verify your timezone, elevation, and station coordinates before uploading data. Detailed setup guidance will be available on our [Setup Instructions](/pws/connect/) page when the platform launches.
Through the upcoming PWS platform you'll be able to share a customizable set of measurements: temperature (current, daily high/low), dew point, relative humidity, barometric pressure (sea-level adjusted), wind speed (sustained and gust), wind direction, rainfall (current rate, hourly, daily, weekly, monthly, yearly totals), UV index, solar radiation, and soil moisture and temperature if equipped. You'll choose whether your station is public (visible to anyone) or private (visible only to you), and you'll control which specific measurements are shared.
