Orbit Communications introduces the FrostAlert early frost detection and warning system.

The FrostAlert warning system helps prevent damage to crops and delivers peace of mind by providing an advance warning alarm of the onset of frost. 

Once activated the FrostAlert early warning system will produce an audible and visual alarm that is triggered by the temperature in the field falling below a programmed set-point, eliminating the need to wake up every few hours to check the outside temperature.

The FrostAlert warning system has switched outputs that can be used to turn on a watering or fogging system, for a programmable period, to help lower the risk of damage to crops.

The alarm system consists of one or more remote sensor units that are installed at locations where the temperature requires monitoring. The remote unit can be located up to several km away from the house and is typically powered by a renewable energy source such as a solar panel. The remote temperature monitoring unit and sends updated temperature readings to a base station located inside either the house or shed.

The base unit receives periodic temperature information from the remote units and compares the received values with the user-programmable trip temperature (temperature where alarm is activated). Typically the trip temperature is set slightly above frost point (2 or 3 degrees Celsius) in order to give plenty of warning before a frost condition occurs.

In event that an alarm is activated, a watering or fog system can be used to help prevent damage by the impending frost conditions. The alarm will automatically reset when the temperature rises 1 degree Celsius above the programmed trip temperature.

The system has an integrated monitor that observes the Radio connection between the house and remote temperature sensing unit, and will activate an alarm if the communication link is weak.

The battery voltage in the remote unit is also monitored and will cause an alarm condition if the battery voltage gets too low.
