The WS-GP2 Weather Station is   ideal for research and environmental monitoring applications Based on the versatile GP2 Data Logger and Controller, users can select the optimal configuration of sensors, power options and communications. 

Flexibility

The GP2 Logger hasthe power and flexibility to handle almost any environmentalsensor, which meansthe weather station can be assimple or as complex as your application requires. Even after installation, it’s easy to expand or adapt the system by adding solar power, for example.  Optionalsensorsinclude barometric pressure, soil moisture, soil EC, UV, PAR, albedo, net radiation, total and diffuse radiation and evaporation.

Storage, communication and power

The GP2 can store 2.5 million readings (typical) in FLASH memory. Data can be collected by laptop via USB/RS232 or remotely using the cellular modem options (see right).   The GP2 has 6 alkaline AA internal batteries as standard with external battery and solar power options available. Up to 7 GP2s can share power and communications using an M12 cabling network.

Advanced features and customisation

For researchers interested in evapotranspiration (see back page), degree days, disease prediction, wind chill factor, dew point, PID control or other custom algorithms the GP2's advanced features open up exciting possibilities. Analog inputs can be fully customised: each channel can have its own input type and recording parameters. DeltaLINK software gives the user control over reading frequency, thresholds and units, and provides recording options for average, min and max, plus specialised wind options  including wind rose, gusts and wind averaging (with direction and vector average). Users can add their own custom sensor types to the sensor library, exploiting the GP2’s detailed configuration options.

The GP2   provides 4 input ranges down to   microvolt resolution with   adaptive auto ranging,   excellent analog accuracy,   and configurable sensor   excitation enabling   it to support nearly all   analog sensors. There is   also an SDI12 Sensor   library (see back page for   more SDI12 details). Calculations based   on the measurements   from several input   channels can be recorded   and displayed as additional   virtual channels (calculated   measurements).
