Weather station with ultrasonic sensors, active output (0-10 V), digital output (Modbus RTU)

The weather station FS6002 is used to detect the most important meteorological parameters. Depending on the configuration, the device provides the measurement data of wind speed / direction, air temperature, relative humidity, barometric air pressure, precipitation and brightness.For a correct determination of the wind direction in mobile use of the weather station, a magnetic compass is integrated in all device variants. Furthermore, a built-in GPS receiver is used to determine the exact world time and geographical position.The wind speed and wind direction is determined by the detection of the 2-dimensional horizontal components of mutually perpendicular ultrasonic measuring sections. In addition, the sound velocity can be used to calculate and output the acoustic virtual temperature. Due to the measuring principle of the ultrasonic transit time measurement, the device is ideally suited to the inertia-free wind gust and peak value measurement.The air temperature and relative humidity are measured by an integrated and accurate combination sensor, which is protected against harmful environmental influences by a water-impermeable but water vapor-open microporous filter.The integrated pressure sensor based on MEMs (micro-electro-mechanical-system) technology is also protected with such a filter.In the measurement of precipitation intensity, the precipitate is measured and calculated contactlessly via the back-reflected signal of a Doppler radar. The intensity of the last minute is extrapolated for the output to one hour.The brightness is recorded by 4 photosensors with a spectral sensitivity curve adapted to the sensitivity of the eyes and the intensity ratio is used to calculate the direction of the light source.The weather station has a built-in heater. This largely prevents an ice and snow on the device.The data output can be analog, as standard signal and / or as digital (MODBUS RTU). 8 analog output channels (0-10 V) are available, 5 channels of which can optionally be configured universally.
