Scottech were the first in New Zealand to offer a simple Frost Alert that utilised cell phone technology that would make a phone call to growers to alert them to frost conditions, and avert massive crop losses.
They also developed the first Frost Flasher system that allowed growers to target specific areas in an orchard for frost fighting by having a simple temperature dependant flashing light that could be seen from the ground or air.
For more complex alarming applications, we can integrate alarms into weather stations or other monitoring systems, that can be triggered on any measured condition. Alarms can be audible, visual, phone calls or text messages.

Many of the weather stations on telemetry are also able to provide alert systems, either by programming the station or installing an autodialler.
