iWeathar Edge V

The iWeathar Edge V is a simplistic self contained easy to install, low maintenance weather station for the cost conscious buyer.



Features include:
 

• Easy to install.
   
• Highly Accurate Wind Readings (NIST certificate available on request).
   
• Completely self sufficient.
   
• Wind, temperature, humidity and barometric sensors come standard.
   
• Includes a Solar regulator with Power management and low voltage battery protection.
   
• Allows for up to 7 analogue sensors and two counter sensors to be connected.
   
• GSM signal strength and Voltage monitoring.
   
• Modem power down / reset circuitry.
   
• Dial-in and reset function.
   
• Extreme accuracy using 12 to 14 bit ADC Resolution.
   
• Implements 1-wire for temperature and humidity
   
• Reverse polarity fuse protected.
   
• Ultra low power consumption 50-100mA.
  
  Ideal for environment impact, construction site and home /light industry wind turbine assessments, the Edge allows up to two (2) anemometers to be connected for wind gradient measurements.
  
  
  
  What additional sensors can be added?
  1.Rain Gauge (0.2mm increments)
  2.Additional Anemometer
  
  or any other sensor with a Digital or 0-5V analogue output.
  
  Standard Package Includes:
  
  1. iWeathar Edge Module
  2. Quad band GPRS modem with antenna
  3. 10-20 Watt Solar Panel and 6A regulator
  4. 1 x Sealed Gel Battery 12V 12A
  5. Wind anemometer and Vane (Davis 6410)
  6. Temperature sensor
  7. Humidity sensor
  8. Attached Radiation shield
  9. Barometric Pressure sensor
  10. Accessories (Serial Cable, Wiring and Weather proof enclosure.)
  
  
  
  Your Requirements
  
  1. Mobile phone Data SIM card for the gprs modem (uses around 20 Mega-bytes of data monthly).
  
  2. Monthly Service Fee, iWeathar provides online software services allowing you access to your stations reports, graphs, settings, wind turbine assessment program, data analysis and much more at R120 per month.
  
  3. Mounting pole and related fixtures. We highly recommend a solid high pole (avoids wind vibration which affects sensor readings) with grounded earth line.

  Each unit is guaranteed for up to 12 months from date of purchase. This excludes lightning damage and other drastic forces of nature (tornadoes, hurricanes etc.)
  
  Please note that iWeather reserves the right to store and sell the weather data at our discretion should you and only when you make the weather data available to the public at large.
  
  Due to the station connecting via 3rd party cellular service providers and low power-outs due to ongoing bad weather (lack of sunlight to the solar panel), data loss may and can occur.
  
  iWeathar does not take any responsibility for loss or damage to the stations data should this ever occur. An additional data logger is available for critical data applications.
  
  Should you not wish to use the iWeathar networks reporting and graphing facilities, you are able to download the raw data in the standard comma delimited CSV format for you to disseminate.
  
  Engineers please note: The iWeathar system calculates wind turbulence intensity from the standard deviation formula only from the final 10 minute maximum and average values and not on a continued sampled basis
