Parameter Measurements

Wind Speed and Direction. The wind meter uses four ultrasonic sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Air Temperature and Humidity. Temperature is measured by way of a highly accurate NTC-resistor while humidity is measured using a capacitive humidity sensor. To help mitigate the effects of external influences, these sensors reside in fan-aspirated housing.

Air Pressure. Absolute air pressure is measured with a built-in micro-electro-mechanical sensor (MEMS). The relative air pressure referenced to sea level is calculated using the barometric formula configured with local altitude input by the user.

Precipitation. Models 100, 400, 600, 700, 800 precipitation sensor works with a 24GHz Doppler radar, which measures drop speed and calculates precipitation quantity and type by correlating drop size and speed. Model 601 has a tipping bucket and offers an optional leaf wetness sensor.

Solar Radiation. The Model 501 thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere(180 degrees field of view). Models 502, 700, and 800 use a silicon photodiode sensor.

Compass. Included on all models with wind measurement, the electronic compass helps orient the module and correlate wind direction automatically.

Lightning Detection. Model 800 only. An integrated sensor analyses the radio wave emission of lightning. It delivers a count of lightning and suppresses man-made electrical discharges with a 5 - 10 km coverage area.
