Harvest Frost G2 System Features

Harvest Frost G2 is coming soon! Some specs listed below may differ slightly from release product.


  • Online Data. Each system has its own configurable web page. Weather trends are visible at a glance as well as complete weather history. All weather data is archived and can be downloaded from your site in csv or plain text format at any time. During a frost event you will be able to see your data coming in every minute. Under non-alarm conditions data is reported back every hour with 10 minute logs.
  • Alarms. The system sends up to four messages (text messages, voice messages or emails) when the temperature drops to the alarm level set by the customer. Other alarms can also be configured: a second temperature alarm, battery voltage alarms, high wind, high temperature etc.
  • Investors. The normal daily weather data is a great way for shareholders to see what's happening at their investment site.
  • Versatile. The solar-powered unit can be placed anywhere on your site. It uses the Vodafone GSM/GPRS network in New Zealand and any GSM/GPRS nework in other countries. The system is also available in a satelilte version. Installation is quick and easy with no technical expereience needed.
  • Wireless Temperature Sensors No wires to install or get damaged! Standard wireless sensors have a range of up to 250 metres while the latest generation high power sensors have a range of up to 1km. No wiring means the sensors can be installed in a few minutes and placed at the coldest and warmest locations so you can get a good idea of the temperature profile during a frost event. Under frost conditions new temperature readings are reported every minute.
  • Growing Statistics. The system calculates Growing Degree Days for your site during growing months, and Richardson Chill Units during the winter months. For an example, go to McGireny's temperature statistics.
  • Calculated Weather Variables. Calculated values such as Dew Point, Wet Bult, Evapostranpiration and Wind Chill are now available. Bacchus Botrytis risk calculations are also available for no extra charge with the addition of a leaf wetness sensor.
  • Rain and Wind Sensors. The standard combination for all Frost G2 systems are the NIST approved Davis anemometer and 0.2mm rain gauge. Updated rainfall totals are available at a glance. Wind data is always useful with both average and gust calculations.
  • Humidity Sensor. With the addition of a humidity sensor both dew point and wet bulb calculations can be done.
  • Soil Moisture Probes. Decagon Echo and Aqualfex soil moisture probes can be added to the system. Every unit can handle multiple probes. If needed the soil moisture probes can be monitored by wireless instead of hard wired.
  • Advanced Wind Machine Monitoring. Many Vineyards and Orchards that have Harvest systems are now monitoring their wind machines. The Frost G2 system can monitor engine rpm, oil pressure, fuel level, engine on/off and battery voltage. With the G2 it is possible to monitor up to 8 systems.
  • Other Sensors. Any system can be equipped with a range of other sensors including solar radiation (used for evapotranspiration), leaf wetness and barometric pressure. We can also monitor a range of other sensors including flow meters, well depth sensors, and a range of other analogue and digital input sensors.
  • Quick View. A special Quick View page is available for on-the-spot management during the operation of wind machines, sprinklers or even in the cockpit of a helicopter. This web page shows the latest temperatures and the temperature trend by means of arrows. See the quickview page for the McGireny Vineyard.
  • WAP Cellphone Page. For in-field use you can also view the live temperature data on any cellphone using WAP (try http://harvest.com/mcgovern).
  • Optional Password. Your web data can be password protected if that's what you need, or you can share the information with your neighbours and in fact the whole world.
  • Large Sites. With the G2 system and high power wireless temperatature sensors there are no problems reaching every corner, dip and high point of your site. With the 1km range of the high power sensors an approximate coverage of 100 acres is possible.
