Air temperature:
A PT1000 measuring resistor is used to measure the air temperature. The sensor is mounted
on a flexible printed board and positioned in the lower section of the housing.
Time / date and geostationary data:
The Weather Station has a GPS receiver with a built-in RTC. This allows it to receive the
position of the Weather Station (degree of longitude/latitude, local altitude) time (UTC) and
date. The GPS receiver does not need alignment.
The built-in RTC (Real Time Clock) is buffered with a backup capacitor and retains its data
without a voltage supply for a period of minimum 3 days.
Position of the sun (elevation / azimuth):
On the basis of the GPS data the current sun position is calculated every second.
Humidity measurement:
A built-in hygro-thermosensor is used to measure humidity levels. The sensor has a small air
exchange volume thanks to its compact design and responds to changes in humidity in
seconds.
A software module uses the relative humidity and air temperature to calculate absolute
humidity and the dew-point temperature.
Inside temperature of housing:
A silicon temperature sensor measures the temperature inside the housing.
GPS-Receiver:
The weather station has a GPS receiver with integrated RTC (Real Time Clock) for receiving
the position of the weather station, and time + date (UTC).
An alignment of the GPS receiver is not necessary.
The integrated RTC is buffered for a period of 3 days.
General information:
After activation of the Weather Station Compact WSC10 the first satellite data are available
after approx. 2.5min.
When receiving the signals from one satellite: time with an accuracy of < 1µs.
When receiving the signals from three satellites: position with an accuracy of <
20m
When receiving the signals from four satellites: altitude, referred to the WGS84-
ellipsoid, with an accuracy < 30m
