Air Communications of Central WI has designed a complete monitoring system specifically for cranberry growers. This gives you the ability to customize the alarm to fit your needs. It consists of a base unit and a field unit. The Base Unit has a large, touch screen display that lets you program the unit the way you want. The Field Unit helps eliminate lightning damage with its wireless sensors, and alerts you if there is a problem with temperature, the circuits or battery. And our Alarm Dialer can now call you when you are away from home, alerting you to changes that need attention.
