Weather Station - ET 107

ET 107


Automated water management depends on precise climate measurements.


High-quality ET Weather Stations measure climate conditions that affect evaporation and transpiration.  ET107 sensors measure; solar energy, wind, humidity, temperature and rainfall. 




Overview

Campbell Scientific weather stations deliver accurate, reliable and timely information. 

An ET107 station consists of meteorological sensors, an aluminum mounting pole, and an environmental enclosure that houses the electronics and sealed rechargeable battery.  The enclosure includes a datalogger for measuring sensors, processing and storing data, and communicating with a computer.  Irrisoft ET Weather Station packages are programmed and configured for the Weather Reach Water Management System.
 
When choosing an ET107 the following options must be considered:

  • Power Supply
  • Communication

Power Supply Options

  • AC 110 Volt AC Power
  • SP 10 W Solar Panel

Communication Options

Weather Reach Servers retrieve weather data stored in the station's datalogger.

  • Cellular IP – A cellular modem enables communication via the Internet.
  • Standard Phone – A modem enables communication over a standard analog telephone line.
  • Network - Internet connection via TCP/IP.
  • Spread Spectrum - Enables wireless point-to-point communications to a computer.
  • Direct Connect – RAD short haul modems enable a wired connection to a computer.
