Data loggers for weather monitoring 

Our weather stations are based around a programmable data logger (typically a CR1000 or CR3000) that measures the sensors, then processes, stores, and transmits the data. Our data loggers have wide operating temperature ranges, on-board instructions, programmable execution intervals, and ample input channels for commonly used sensors. Wind vector, wet bulb, histogram, and sample on maxima or minima are standard in the data logger instruction sets. Most sensors can be measured directly—without external signal conditioning. 

Data are typically viewed and stored in the units of your choice (e.g., wind speed in mph, m/s, knots). Measurement rates and data recording intervals are independently programmable, allowing calculation of 15-minute, hourly, and daily data values from 1-minute or 1-second measurements, for example. Conditional outputs, such as rainfall intensity and wind gusts, can also be recorded. The program can be modified at any time to accommodate different sensor configurations or new data processing requirements. If needed, channel capacity can be expanded using multiplexers, including a model designed specifically for thermocouples. 

Weather Sensors 

Almost any meteorological sensor can be measured by our data loggers, allowing stations to be customized for each site. Typical sensors used on our stations include, but are not limited to: 

• • Wind speed and direction 
  • Solar radiation 
  • Temperature (air, water, soil) 
  • Relative humidity 
  • Precipitation 
  • Snow depth 
  • Barometric pressure 
  • Soil moisture 

In some locations, hydrological sensors provide additional measurements, such as water level of a nearby stream. 

Data Retrieval 

We offer multiple communications options for data retrieval, which can be mixed within the same network. Telecommunications options include short-haul, telephone (landline, voice-synthesized, cellular), radio frequency, multidrop, and satellite. On-site options include storage module and laptop computer. 

Software 

Our PC-based support software simplifies the entire weather monitoring process, from programming to data retrieval to data display and analysis. Our software automatically manages data retrieval from networks or single stations. Robust error-checking ensures data integrity. We can even help you post your data to the Internet.
