| With Passive ShieldingThe Wireless Temperature/Humidity Station measures relativehumidity and air temperature. The passive solar radiation shield is made of a proprietary plastic designed for highthermal reflectance and low thermal conductivity. It can be used with any wireless Vantage Pro2 weather station aswell as all other compatible wireless stations.The humidity sensor is a thin film capacitor element. A dielectric polymer layer absorbs water molecules from the airthrough a thin metal electrode, which causes a change in capacitance proportional to relative humidity. Thetemperature sensor is a precision thermistor that produces a resistance change proportional to temperature. Thesensors are mounted next to one another in the sensor interface module "SIM" to ensure a close correlation betweenrelative 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 passivesolar radiation shield. Please refer to the WeatherLink for Vantage Pro and Vantage Pro2 specification sheet foroptional data logging and charting capabilities available for this product.GeneralOperating Temperature . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +150 F "-40 to +65 C"Storage Temperature . . . . . . . . . . . . . . . . . . . . . . . . . . . -50 to +158 F "-45 to +70 C"Current Draw, Sensors & Transmitter only. . . . . . . . . . . . 0.14 mA (average), 30 mA "peak" "from external power source"Battery: Sensors & Transmitter . . . . . . . . . . . . . . . . . . . .
