The VSP3 Vosponder, manufactured by DACOM Technologies, Inc., allows customers to call their site using a hand-held UHF or VHF radio and receive a verbal report of real-time site conditions. Ideal applications include fire weather, avalanche forecasting, local weather monitoring, irrigation control, water level monitoring, water quality, and industrial process control.
Customers initiate voice transmissions by pressing buttons on a hand-held radio. Once initiated, the Vosponder uses an SDI-12 interface to collect raw digital data from a Campbell Scientific datalogger. The Vosponder then converts the collected data into natural human speech and recites a verbal message.

Features
