The passive solar radiation shield is made of a proprietary plastic designed for high thermal reflectance and low thermal conductivity. 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® for Vantage Pro2 & Vantage Vue specification sheet for optional data logging and charting capabilities available for this product.Genera lOperating 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 . . . . . . . . . . . . . . . . . . . .
