Orbit Communications announces the release of FrosAlert Frost detection and warning system.
FrostAlert frost early warning system helps prevent damage to crops and gives peace of mind by providing an early warning alarm of impending frost conditions. Instead of the requirement to wake up every few hours to check the outside temperature FrostAlert early warning system will activate an audible and visual alarm when the temperature in the field falls below a programmable set-point. The FrostAlert frost warning system has switched outputs that can be used to turn on a watering for fogging system for a programmable period to help lower risk of damage to crops as a result of frost.
The Frost Alert 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 regular temperature update information to a base station located in 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 built-in monitoring of the Radio link between the house and remote temperature sensing unit and will activate an alarm if the communication link is not healthy. The battery voltage in the remote unit is also monitored and will cause an alarm condition if the battery voltage gets too low.
