Harvest Electronics, in co-operation with the Solano Irrigation District and the Suisun Valley Vintners and Growers Association, have donated this system for the benefit of all growers in the area.
This is a complete 3G cellular based solar powered weather station. The system reports at least every 30 minutes and immediately for alarms (eg. frost or heat). It has sensors for temperature (wired and wireless), rainfall, wind speed and direction, soil moisture, humidity (used for calculating dew point and wet bulb temperature) and solar radiation (used to calculate evapotranspiration). Text messages, voice messages and emails can be sent when alarm levels are exceeded (eg, frost alarm, heat alarm, high rainfall, high wind).
Growing season for these calculations is 1 Jan to 31 Dec. GDD (Growing Degree Days) are calculated inside the season dates, RCU (Richardson Chill Units) outside.
