Frost Alarms

The Harvest solar powered online frost alarm is the most widely used online frost alarm system in New Zealand. The system is extensively used throughout vineyards, orchards and farms as an advanced frost alert system with live data reporting during frosts. In many cases it serves the dual purpose of collecting a variety of weather variables as well as sending frost alarms. This system will give you the ability to manage and protect your assets with more precision than ever previously possible.

The picture below shows the system control unit with the optional wind sensor and rain gauge. The case is custom designed polished stainless steel giving strength, durability and weather proofing. It comes with a bracket to mount on a Warratah or any T-post with an optional pipe mount bracket.

Each unit supports multiple wireless and hard wired temperature sensors. The standard wireless temperature sensors can be placed up to 250 metres away from the base unit while the latest high power wireless temperature sensors offer ranges of up to 1km. The wireless technology enables the temperature sensors to be installed in a few minutes and placed at the coldest and warmest locations on your property enabling excellent temperature profiling. Under frost conditions new temperature readings are reported every minute.

Wind Machine Monitoring

Leaf Wetness Sensor

The systems are capable of providing a complete array of weather variables such as wind speed/direction, rain fall, relative humidity, barometric pressure, solar radiation, evapotranspiration, leaf wetness, Bacchus Botrytis risk, wet bulb, dewpoint, wind chill, soil moisture, soil temperature, water temperature and UV radiation.
The systems can also monitor irrigation systems for water resource consents (water flow rate, accumulated totals, well depth and conductivity) and wind machines (battery voltage, oil pressure, fuel level, rpm and run hours).
