Wireless Temperature/Humidity Station
With Passive Shielding
The Wireless Temperature/Humidity Station measures relative humidity and air temperature. The passive solar
radiation shield is made of a proprietary plastic designed for high thermal reflectance and low thermal conductivity.
It can be used with any wireless Vantage Pro2
™
weather station as well as all other compatible wireless stations.
The humidity sensor is a thin film capacitor element. A dielectric polymer layer absorbs water molecules from the air
through a thin metal electrode, which causes a change in capacitance proportional to relative humidity. The
temperature sensor is a precision thermistor that produces a resistance change proportional to temperature. The
sensors are mounted next to one another in the sensor interface module (SIM) to ensure a close correlation between
relative humidity and temperature readings. Relative humidity and temperature are used to calculate dew point.
The Wireless Temperature/Humidity Station includes temperature and humidity sensors, transmitter, and a passive
solar radiation shield. Please refer to the WeatherLink
