The Dew/spray drift alarm consists of a battery powered transmitter/antenna/surface mositure sensor combo (intended for temporary deployment in a crop) that radio links to a plugpack powered receiver when dew forms.
Provide a wake up alarm when dew forms during the baling season so that harvesting of lucerne (alfalfa) or other moisture sensitive crops can begin.
Can be linked to an auto dialler so that contract harvester operators can be notified by phone when cropping conditions are correct at a target property.
Is quick to deploy, simple in concept, has application as a spray drift sensor for cotton growers, and an alarm back up in traditional data logged situations such as leaf wetness monitoring for disease control.

Can't run a cable? Use a radio link instead! Radio links are the cheap alternative to start and stop irrigation pumps, monitor alarms, or remotely measure analogue signals from machines, buoys, and other isolated equipment, without the need for a radio license.
Radio Links will turn problems into extra income for contractors, save money for plant maintenance departments, and give much greater freedom to electrical design staff.
