Harvest G2 Frost Alarm System Features

Frost G2 System

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 30 minutes 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 is happening at their investment site.

Versatile. The solar powered system can be placed anywhere on your site. It uses the Vodafone GSM/3G or Telecom XT (3G) network in New Zealand, Telstra NextG (3G) in Australia, and AT&T GMS/3G in USA and any GSM/3G network in other countries. Installation is quick and easy with no technical experience needed.

Wireless Temperature Sensors No wires to install or get damaged! Standard Short Range Remotes (SRRs) have a typical range of up to 300 metres (330 yards) while the Long Range Remotes (LRRs) have a typicalrange of up to 2km (1.3 miles) depending on terrain. 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.

Calculated Weather Variables. Calculated values such as Dew Point, Wet Bulb, Evapotranspiration 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 G2 systems are the NIST approved Davis anemometer and 0.2mm (0.01 inch) 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, Aquaflex and Sentek soil moisture probes can be added to the system. Every unit can handle multiple probes. If needed the Decagon and Aquaflex soil moisture probes can be monitored by Long Range Remotes (LRRs) instead of being hard wired.

Advanced Wind Machine Monitoring. Many vineyards and orchards that have Harvest systems are now monitoring their wind machines/frost fans. The G2 system can monitor engine rpm, fuel level, engine status (on/off) and battery voltage.

Other Sensors. Any system can be equipped with a range of other sensors including solar radiation (used for evapotranspiration), leaf wetness, barometric pressure, water depth sensors and water pressure sensors.
The system can also monitor a range of other sensors including flow meters and a range of other analog and digital input sensors most of which can be monitored by hard wiring to the base system or by the use of Long Range Remotes (LRRs).

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 trends.

WAP Cellphone Page. For in-field use you can also view the live temperature data on any cellphone using WAP.

Smartphone Compatability. Webpages are now accesible via a smartphone friendly webpage -

Optional Password. Your 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 Long Range Remotes (LRRs) there are no problems reaching every corner, dip and high point of your site. With a range of up to 2km (1.3 miles) the long range remotes give a maxiumum coverage of up to 1,250 hectares (3,100 acres).
