Wireless Integrated sensor suite for use with Vantage Connect, Vantage Pro2 and Vantage Vue consoles or Weather Envoy and WeatherLink. The corrosion-proof sensor suite combines a rain collector; solar irradiance, temperature and humidity sensors; and anemometer into one package for rugged reliability and performance.
Features:
- Wireless sensor suite with integrated sensors for temperature/humidity, rain and solar irradiance.
- Temperature and humidity sensors are housed inside a radiation shield. The shield protects against solar radiation and other sources of radiated and reflected heat.
- Detachable anemometer provides wind speed and direction and can be sited up to 12 m above the other sensors.
- Ability to add UV sensor.
- Add cellular-based, solar-powered Wireless Vantage Connect to upload your weather data to the internet. Get real-time alerts for frost, evapotranspiration, high winds or other conditions you specify.
- Comes with the new Aerocone rain gauge offering more accurate measurements in strong wind conditions.
