Station - Sensors
The station weather has a group of integrated sensors (Integrated Sensor Suite – ISS) that collects outside weather data and sends the data to a Vantage Pro2 console or Weather Envoy. Wireless and cabled versions of the ISS are available, as well as Standard and Plus versions. The Wireless ISS is solar powered and sends data to the console via a low-power radio. The Cabled ISS send data and receives power via the console cable.
The standard version of the ISS contains a rain collector, temperature sensor, humidity sensor and anemometer. In addition to the standard weather features, the ISS Plus adds a pre-installed solar radiations sensor and an ultra-violet (UV) radiation sensor. Temperature and humidity sensors are mounted in a passive radiation shield to minimize the impact of solar radiation on sensor readings. The anemometer measures wind speed and direction and can be installed adjacent to the ISS or apart from it.
On an ISS Plus, the additional solar and UV sensors are mounted next to the rain collector cone. Separate solar and UV sensors are available to upgrade a standard ISS.
The Sensor Interface Module (SIM) contains the “brains” of the ISS and the radio transmitter. The SIM is located on the front of the radiation shield in the SIM box. The SIM collects outside weather data from the ISSS sensors and then transmits the data to the Vantage Pro2 console or Weather Envoy.
