The WindOne system  is designed to provide an affordable and easy-to-use solution for wind site evaluation and wind generator power performance evluation. It easily supports both simple and complex monitoring applications. The WindOne system records wind speed, gust, turbulence intensity (standard deviation/average wind speed) and direction, as well as the time and date,  battery voltage, and other optional  important wind parameters, like tempearture and atmospheric pressure.
The WindOne is capable of recording wind speed from one (up to eight!) anemometers, making it ideal for more complex studies involving multiple wind speed instruments and other sensors.

The accuracy is excellent by using a two paremeter calibration: slope and offset of anemometer and meets international standards (like WMO/IEA). Optional individual calibration certificates available (MEASNET),
resulting in an excellent 0.1 m/s accuracy.
The 16 bits conversion & calculation of values assure an unbeatable accuracy at very low costs.

The ultra low power consumption of appr 100 uA makes it ideal for remote applications, running at safe battery pack (no solar panel required, also not if the wireless GPRS option is installed!)

The WindOne records directly to a Secure Digital (SD™) card (128MB to 2GB)  to provide reliable data storage. An inexpensive SD™ card will store years of data at 10 min intervals.

An optional wireless GPRS internet connection is possible: receive datafiles automatically at a  server! With optional online graphs, see below.

Using the recorded data is simple. The SD™ card is inserted into a card reader attached to the USB port on your computer and will then show up as a drive.
Microsoft Excel  or practically any spreadsheet program can be used to view, graph, and analyze your wind data. We also supply ready to use wind utilities for calculations of eg Weibull parameters, Energy production, Frequeny distribution etc.

Logs wind sensors, weather sensors, analog inputs, and system parameters

• Anemometers (average wind speed, max, min and standard deviation)
  • Pre-calibrated (1 to 8 pcs)  for anemometers from Maximum/ NRG and Davis Instruments 7911/6410 or First Class anemometers
    Optional MEASNET calibration certificate and 16 bits resolution
    for highest accuracy (0.1 m/s)
• Wind vane (wind direction, 1 to 6 pcs)
  • Works with wind vanes from EKOPOWER DIR21+, NRG 200P, and Davis Instruments. 7911/6410 or other types.
• Thermometer (temperature) and atmospheric pressure sensor
• Optional inputs, like (12 or 16 bits)  0-5 VDC or 0/4..20 mA, counters, status, etc
• Real time clock
• Many optional sensors available: voltage, current, temperature, relative humidity, rain fall, light intensity, kWh (energy) and others

Possibilities:

• Adjustable sampling/logging interval: The sample interval is minimal 1 sec, logging interval is adjustable from 1 to 10000 samples (average, maximum, minimum and standard deviation). For most applications, a10 min interval is ideal.
   
• Sensors and Mounting: Our anemometers and wind vanes mount directly to with an stainless steel M5 bolt to a vertical hole. The wind sensors can be located hundreds of meters away from the WindOne system. Optional mounting arms are available.
   
• Display: A laptop (with RS232 or USB interface) can function as super-display for reading current information and is used for configuring the data logger, using the supplied control software:
  A simple menu-driven interface makes setup easy.
   
• Optional Ultra low power Wireless GPRS connecton for receiving data
  at your server  via internet and with optional online graphs
  
  The WindOne system is also available with Ethernet connection
  with built in webserver, using the iBOX datalogger module.
  Communication possible via ethernet and/or  internet.

• Power Source: The WindOne operates directly from any DC voltage source between 6 and 14 volts. Ultra low Power consumption: approximately 100 uA, which allows the WindOne to be powered from the wall, alkaline or lithium  batteries, or solar power systems, or AC adaptor
   
• Clock: An accurate real-time clock is used to time-stamp each measurement. The clock is battery backed and is accurate to within some minutes per year or better.
   
• Installation: The WindOne  mounts directly to a pole or mast using special clamps.

Wind sensors:

Other sensors/transducers:
additional channels possible for eg solar radiation, power, status, 4..20 mA
 and (AC and DC) power transducers for power performance evaluation.
 see products for more available additional sensors and transducers

Sensor accessories:
To make the installation easier, accessories for mounting wind sensors are possible with:
- tripod
